If you are after an affordable cordless lawn trimmer, the Erzneaoch 21V will have most likely already caught your eye. It retail prices between £40 and £60, so it's one of the lowest-cost options around — a tempting offer for keen gardeners or anyone with minimal lawn maintenance. With thousands of positive reviews and claims of robust performance, this product delivers much: ease of use, power, and versatility, without the hassle of leads.
Long Term Test
But as with so many cheap garden tools, the true test comes in long-term use. Is the low cost a true bargain, or does it involve trade-offs in quality or longevity? This review examines closely what the Erzneaoch cordless grass strimmer provides — and what potential purchasers need to look out for.
Key Features
At its heart beats a copper motor rated at 650W with a no-load speed of up to 6,000 RPM. While the product sometimes in listings makes a claim for 750W and 11,000 RPM, one should note that different lists carry different spec — something which we will make a thorough point of in this review. What's clear, however, is that it's only suitable for light to medium trimming work, and not heavy clearing work.
Assembly
At 1.4kg (about 3.8 pounds), the device is marketed as lightweight and ergonomic. Its telescopic shaft can be adjusted from 40 to 53 inches, and the head is tiltable at 90° — ideal for reaching strange angles or edges. Assembly is required but usually referred to as simple.
Battery System
The Erzneaoch strimmer has a 21V battery pack and two included 2000mAh lithium-ion batteries, offering about 30 minutes of run time between charges. It should be fully charged before initial use to get the best out of it. Refilling takes about 2–3 hours per battery, which is quite normal on this price range.
Cutting Attachments
One of the standout aspects is the array of cutting blades available. The box includes ten plastic blades, as well as additional trimmer accessories for grass, weeds, and even small bushes. A glove pair comes included as well, which is a nice addition — although again, how well the accessories hold up long-term is something to monitor.
Customer Feedback
Customer feedback for the Erzneaoch 21V battery-powered strimmer shows a varied but informative picture. The majority praise its affordability, ease of use, and overall performance for light garden use. Problems with longevity and inconsistent build quality appear frequently — especially from those expecting commercial-grade durability.
Value for Money
Arguably the most frequent of this strimmer's accolades is its affordability. On the market for under some of its competitors and with two batteries and a large blade set included, it's largely considered a great buy for small to medium-sized jobs around the garden. Several users have dubbed it "worth the money" or "good value for the money" particularly when taking the provision of extra accessories into account.
Battery Life
The battery performance of the strimmer is also a plus point. The two 2000mAh batteries that come along last for 30–60 minutes according to most users, which is more than enough for most home gardening work. Charging one when still in use with another provides an added plus, and as many declare, battery life was beyond expectations at this price point.
Lightweight and Ease of Use
Ease of use is one of the best aspects of this tool. Clients refer to it as "lightweight," "easy to assemble," and ideal for those who may have trouble operating the larger or more complicated equipment. Some even mention that their husbands or elderly family members can easily use it, thanks to the thin profile and ergonomic design.
Blade Variety and Functionality
The introduction of different blade types — metal, plastic, and wire — has been trendy. The metal blades, in particular, are positively spoken about for their performance with tougher materials like nettles and thin twigs. Certain customers do make mention that they have yet to use all the blade types, and others experience breakage when used for the first time, so one can assume that the performance will vary depending on where and how the blades are used.
Reliability and Durability
Durable is the first area where feedback is key. While the tool performs well in light garden conditions, some customers warn that it's not for heavy duty or commercial use. Feedback of the plastic blade breaking too easily, attachments breaking on their first use, or the motor burning up after 15 minutes is not rare. Some reviewers say that the product feels flimsier than expected, especially compared to how it's represented in sales photos. (there are more plastic blades than shown in the image below)
Positive Reviews
Many customers of the Erzneaoch 21V cordless strimmer report satisfaction rates that are very high, particularly for people with small gardening needs and a bargain-hunting inclination. While it is understandable that this isn't a heavy-duty or professional model, people who entered into it with practical expectations were surprised by how much of a machine it was.
Impressive for the Price
One of the most common themes of positive remark is simply how much kit you get for your money. Sounding like "a great deal of kit for little money" and "blinder for the cash" gets across the overall opinion that this strimmer delivers more than its price. Most people comment that it has two batteries, a charger, and range of blades included — things that are extra on other brands.
Lightweight and Easy to Use
Customers also consistently remark on how light and easy to handle the strimmer is. One customer stated his wife liked using it because it was extremely light and easy to handle, and another liked that the cordless design prevented tripping over wires — a nice plus for people with mobility or balance issues. The simplicity of assembly and use also adds to the appeal, especially for individuals who do not want to fool around with complicated or heavy equipment.
Gallant Performance on Thick Grass
For cutting power, several users have found great performance, such as in challenging conditions. A very astute reviewer employed the strimmer on grass that had built up to 8 inches high over winter and was impressed at how it "blitzed it with ease." They also noted the simplicity of use of the various cutting blade types and how the product was very powerful for cutting different types of foliage — from light grass to more dense growth like small branches (though some hadn't utilized each blade type yet).
Overall Satisfaction
For the majority of users, this product simply does what it promises to do — and sometimes even a little extra. Testimonials like "fantastic piece of kit," "great wee trimmer," and "excellent purchase, well recommended" suggest a general feeling of satisfaction from frequent users. Users who found the product met their expectations were usually amazed at how much they got for their money.
While most customers are contented with the Erzneaoch 21V cordless strimmer, a significant majority have more nuanced experiences. These customers' reviews suggest that, while the product has outstanding selling features, it also comes with trade-offs — particularly in terms of build, accessories, and user fitting.
Performance Varies by Task
A repeating theme among mixed reviews is that the strimmer does a good job — but only within some constraints. For instance, customers praised it for its ability to handle light to medium gardening duties, especially when equipped with metal blades. Others resented, however, that more fragile plastic or wire attachments were very brittle and far less durable, snapping after a few minutes of use or when they struck slightly harder surfaces like fence posts.
Several commentators noted that it's "perfect for small gardens" or "areas where it's just grass," but warned that it is not for high-traffic or overgrown grounds. One customer had a scary experience when the motor overheated and began to smoulder after just 15 minutes of operation and thus sent the machine back.
Accessories and Assembly: A Mixed Bag
Insertion of other blade types and accessories is generally attributed but complained of as being vague. The instruction manual has been called vague or incomplete many times, and this creates confusion — especially among new users. People complained they were forced to "guess" through the assembly process, and others said some attachments arrived damaged or missing.
For experienced gardeners, this was not a showstopper, but novice gardeners may find the steep learning curve unnecessary.
Quality Control and Minor Design Flaws
Several customers mentioned quality inconsistencies, including misaligned parts, a grip handle that will not stay on, or ill-fitting, small gloves. One customer mentioned that the cutting head was smaller than advertised, at under 8 inches. These are slight flaws in and of themselves, but they contribute to an overall impression that this is a budget product with an occasional rough edge.
Another user also complained of receiving replacement blades instead of the strimmer itself due to what appeared to be a listing or shipping mistake - albeit a one-off.
Battery Life and Power: Expectations Matter
Battery life also got mixed reviews. Some people were astonished — 30 to 60 minutes on a single charge - but others noticed much shorter lifetimes of around 15 to 20 minutes, particularly when demanding more out of the tool. Once again, the impression is that this tool is fine within constraints but not to be taken to extremes.
Negative Reviews
While some customers enjoyed the light work in the garden with the Erzneaoch cordless strimmer, many others had a very different experience. Complaints in negative reviews cover issues of build quality, usability, safety, and reliability, suggesting the product may not be able to fulfil its promise or customer expectations.
Build Quality and Durability Issues
The majority of the customers lamented the material build and quality of the strimmer as substandard. Some of them described the unit as "flimsy," "toy-like," or "cheap rubbish" and bemoaned that vital components were shattering easily or failing to fit altogether.
"Cutting head unit looks MUCH flimsier than on the advert!!!" / "Too light to be effective – Not great, looks good but doesn't work."
Others lamented that the product fell apart after use for just a little while: "Used only for the second time before it fell apart, not impressed." / "Lived for 10 minutes. worst trimmer ever."
Missing and Defective Parts
One of the most common themes in the worst reviews was that products received came missing parts or parts that were faulty. Customers complained about missing screws, bolts, instruction manuals, and even essential parts required for assembly.
"Missing one bolt and the nut that is supposed to secure the second handle." / "Missing pieces." / "Instructions missing… paper is extremely cheap in appearance and cheap feeling."
For some, this made the product unusable straight from the box, requiring returns or hours of looking for replacement parts.
Battery and Power Issues
Again, another major reason for frustration was the poor-performing battery and uninspiring motor on the strimmer. Others complained that fully charged batteries lasted only 5–10 minutes, and in some cases, the strimmer would not even turn on.
"Batteries only last for about five minutes." / "No power on fully charged battery… wouldn't cut through butter, never mind grass." / "Motor is not enough to power any serious cutting or trimming."
For a cordless tool that could possibly handle a decent amount of garden upkeep, the short battery life and inability to cut power were roadblocks for users.
Safety Concerns
Others had concerns raised about the safety of operating this tool. One reviewer explained that the metal saw-blade attachments seemed risky and out of place in a low-maintenance home garden, with children or pets present.
"I myself will not use these metal cutters… on the grounds of avoiding an accident in the garden with other people around." / "Has anyone within the UK Health and Safety Business actually checked that this product is safe to use?"
These are objections not just against the shape of the blade, but also general worries regarding the lack of quality control and safety testing.
Unclear or Missing Instructions
Assembly appears to be an ongoing issue — compounded by missing or no detailed documentation. Purchasers reported that the item arrived with no instruction manual and that it was frustrating or impossible to assemble the components together.
"Instruction book would have been useful… article is extremely cheap-looking and flimsy." / "Can't assemble - the pieces won't fit."
Without assistance, even frequent users were getting stuck, and new users had no chance of having the tool properly installed.
Not Fit for Purpose
The most severe criticism was from customers who simply said the product was unusable or not fit for purpose. These users were extremely irate and felt deceived by the product's packaging and marketing.
"Regret buying it — not up to the job." / "I got nothing out of this product." / "Don't buy — wasted thirty pounds."
Bad Value Even at Affordable Price
Other customers confessed the product was affordable but grumbled that even low expectations weren't met. In their opinion, the Erzneaoch strimmer was an example of "you pay for what you get"—and, in their instance, not even that.
"Should have known it would be useless just from looking at the price." / "It's like a toy for a child… product quality is terrible."
Summary of Common Complaints
Missing or incompatibly supplied parts / Incompletely manufactured motor and soggy cutting / Batteries with short life (as low as 5 minutes in some individual cases) / Breaking blades after use / Metal attachment safety concerns / Missing or incomplete instructions / Difficult or impossible to put together / Perceived as cheap, flimsy, or hazardous.

Bottom Line for Buyers
The Erzneaoch 21V cordless strimmer is a good buy if:
- You like an inexpensive, lightweight strimmer.
- You need a cordless tool for occasional or light yard chores.
- You’re comfortable with DIY assembly and possibly troubleshooting fitment issues.
However, this tool is not recommended if:
- You need something for thick weeds, dense brush, or professional use.
- You expect premium build quality or strong durability.
- You are new to garden tools and need clear instructions or robust safety features.
Final Verdict: Not Recommended
After going through dozens of user experiences in detail, it's clear that while the Erzneaoch 21V Cordless Strimmer itself may appear appealing as it's an inexpensive product with beautiful accessories, it fails to deliver where it is most required — power, strength, and reliability.
Common Complaints
The overwhelmingly common complaints of flimsy construction, broken blade-prone, weak motor, and anaemic battery performance make this product difficult to recommend to the general consumer. The inclusion of multiple blades and two batteries is a nice touch, but it doesn't offset the lack of cutting power and dubious quality control.
Frustrations
While a handful of users with minimal gardens and very light trim needs found some use for it, most found it lightweight, infuriating, or downright dangerous to use. For a garden tool — especially one with metal cutting blades — that's not a compromise you're going to make.
⭐ Rating: 1 out of 5 stars
We do not recommend this strimmer to the public at large. The risk of disappointment — or worse, injury — is too high. Invest your cash in a better-known, safety-proven brand that cuts better and lasts longer.
