The top of our list is the Terratek 20V Cordless Strimmer. This cordless strimmer is a great-value product that combines both trimming and edging capabilities in one strimming package.

What separates this wireless unit from many others is that it comes as standard out of the box with two batteries, meaning that you've got twice the amount of juice for strimming. Each battery last about 40 minutes, so you've got an hour and a half of non-stop strimming power on tap. Battery recharge time isn't particularly fast at 3-5 hours, but we can't see anyone needing more strimming after 90 minutes of action.

Weighing in at just 2kgs, the Terratek 20V Cordless Strimmer is also light, and it comes with large 25cm trimming diameter and quick change blades. These blades just snap in and out of the blade housing, making replacing them easy. Throw in the fact that this system can also edge with an adjustable height of 95cm to 115cm, and comes with a 2-year warranty, and it's clear to see it is a very strong all-round package. And especially so at its budget price point.

To see how this model performs against a top-rated rival, then read our Terratek 20V vs Ego ST1510E (opens in new tab) comparison feature.

Is there anything more faffish than having to wind springy nylon line around a strimmer spindle? You know the scenario. For some unknown reason the line suddenly stops feeding through while you're trimming so you remove the lid on the line feeder and – zing – the whole lot springs out in one big tangled mess. You then spend the next 15 minutes trying to wind it back on the spool only to discover you didn’t wind it on as well as they did at the factory and now it’s worse than before. So you chuck the whole damn lot into the shed where it still resides to this day.

Ego feels your pain and has come up with the answer – a pro-spec cordless whipper snipper that self winds. Simply grab a decent length of Ego’s industrial strength 2.4mm nylon line, feed it through the head and hold the ‘Powerload’ button. Voila, the entire line is mechanically rolled up in just 10 seconds. This is groundbreaking stuff, dude.

The strimmer itself is equally amazing. Although it’s quite heavy, it’s so well balanced that you don’t really notice the weight when using it. What you will notice is how superbly well it performs. Unlike most strimmers that have just one short line spinning around, The Ego ST1511E has two and a combined cutting area of 38cm. This not only speeds up the process noticeably but it also makes it more efficient, which in turn leaves more time for important leisure activities like lobbing water bombs at the kids. Its small unassuming cutter head, meanwhile, features a brushless motor that will likely go on running longer than you will. 

Ego’s battery tech is among the very best and this strimmer can be used with a variety of the company’s 56v batteries. The 2.5Ah version provides about 30 minutes of trimming time while its 7.5Ah version goes on running for up to 90 minutes. If you have a large lawn and the financial wherewithal, then this is unequivocally the weed whacker for you.

Great performer

Reasons to avoid

-
Blades can chew up quickly

The first thing you notice with the Gtech GT50 strimmer is how light it is. At 1.85kgs, this model is easy to hold and use, plus it could strim the neighbourhood and still have enough energy left to lift a Pimms. Actually, that may be a bit farfetched since the battery only lasts about 30 minutes. Nevertheless, from experience, 30 minutes is all it takes to trim the edges of even a moderately large lawn.

Where most other grass trimmers use annoying ‘string’ spools that always, ALWAYS, either jam up or unravel, this one uses a single hover mower-style plastic blade that just clips on. Sure, it wears down quite quickly and deforms at the tip when you get too close to the bordering brick wall, but it in all essence it cuts just as efficiently as a string-based model, only without the agro. And when it’s time to change blades, simply clip on another (Gtech provides a large bunch of them with the product).

Sometimes a product comes along that blows the competition over the garden wall. This is one of them. Make sure you shop our Gtech discount codes (opens in new tab) to snap up the best deal.

Not great at tackling lots of weeds

The Worx WG163 is one of a few two-in-one tools on our list, acting as a grass trimmer and wheeled edger in one. Worx promise quick, hassle-free conversion between the modes and a handy auto line feed, both of which mean you won’t get slowed down mid-landscaping. 

The company includes two li-ion batteries into the bargain, so you can keep using one while the other recharges. A 90-degree pivoting head also makes it easier to trim tricky spots, so if you have lawn furniture, a trampoline, or a tricky-shaped garden, it may be a good buy.

You can see how this strimmer stacks up to our number one choice in our Terratek 20V vs Worx WG163 (opens in new tab) comparison feature.

Telescopic extension could be a little longer 

There’s more to this heavy-duty electric Black & Decker trimmer than meets the eye, not least that it’s lighter and more manoeuvrable than you might think on first glance – but there’s also the fact that it’s part trimmer, part edger. Despite it's size and shape, it's easy to use and reaches even the trickiest of edges.

According to Black & Decker, all it takes for a professional, precise finish is a quick switch to vertical mode, and the innovative Wheel Edge Guide will do the rest. In the arena of cheap corded strimmers, this one is well worth a whirl.

6. Stihl FSA 57

Best cordless model for reliability

Specifications

Type: Cordless
Cutting area: 28cm
Edging?: No
Weight: 3.5kg

Reasons to buy

+
High powered sward trimming
+
Stihl reliability
+
Double-line spooling system

Reasons to avoid

-
Quite heavy

This high-end model features a double-line spool which is more efficient than a single line, obviously. The jury’s out on how long before something goes awry with the spooling system but it looks robust enough and, we hope, reliable.

The FSA 57’s 28cm cutting diameter is perfect for larger lawns but you’d be better served with the larger and longer-lasting AK 20 battery (40 minutes) rather than the AK 10, which lasts for about 20 minutes.

The FSA 57 features a length adjustable shaft, an adjustable loop handle and a comfy trigger grip that feels secure in the hand. This grass trimmer is heavier than some others and you will likely feel like you’ve done a workout after several minutes of using it but, hey, it trims superbly well and, given Stihl’s rosy reliability record, it’s likely to go on running longer than most.

There's a cable to deal with

There's a lot of value in the Flymo Contour 650E electric line trimmer, not least because it can act as both a grass trimmer and edger in one unit. It’s equipped with 10 metre cord and delivers a mid-tier cutting width of 30 centimetres, which will be more than enough for most gardens. This is especially true as this model delivers a dual auto line feed system, meaning that it is more robust than cheaper strimmers.

The downsides to this strimmer are really only two-fold: firstly, it is not cordless, so you have to deal with a power cord, and secondly its build is very ABS plastic heavy. This makes it lighter to use, though, admittedly, but it does the job well even if it doesn't look too impressive.

It uses a cable

This electric edger is far from a one-trick pony, offering up strimming as well as edging capabilities for all-round neatness in the garden. Using EasyEdge technology, the spring-assisted change support promises to make switching between modes easy, and the live tool indicator lights up when plugged in so you know you’re safe to start. 

Reviewers loved how powerful it was on both fronts, while the protected spool cover means that it won’t get away from you and accidentally mulch your prized begonias – good to know! Of course, as it's not cordless, you will have to deal with a cable so keep that in mind when you add it to your basket.

Quite easy to accidentally turn off mid strim

UK-based Cobra waltzes onto the lawn with a cracking strimmer that is both light in the hand and ergonomically styled for effortless strimming. It’s infinitely adjustable from shaft and handle to base and even comes with a pair of wheels for edging lawns to OCD perfection (simply twist the head 45˚).

This model features two cutting speeds: Eco and Turbo. To use, hold in the ‘on' button for a few seconds and it will default to Eco mode which is ample for most strimming needs. If the grass is really long or straw like, switch it to Turbo mode and it’ll slice through it like butter. 

Unfortunately, the ‘on’ button is quite easy to turn off accidentally with your thumb mid strim so bear that in mind should it suddenly cut out and you start panicking that it’s run out of juice. You can safely expect between 25 and 30 minutes of strimming time per charge and a charging time of around two hours. It comes with one 24v battery.

Cobra produces a wide range of great garden machinery and this model’s a case in point. Being of British origin, you should have no issue sourcing its products and spares.

24-minute run time not ideal for huge gardens

This Ryobi strimmer is powered by a 2.0Ah lithium-ion battery that delivers about 24 minutes of operation before needing to be recharged – that’s more than enough time for any small to medium size garden. Naturally, though, if you have a very large garden then expect to buy additional batteries or wait for a recharge.

The cutting path of the Ryobi strimmer is 25cm, which is about average. However the lower hand grip isn’t adjustable like other models so you might find it’s not as comfortable to use if you’re short in stature. On the plus side, it does feel light in the hand.

Reasons to avoid

-
Turbo reduces battery life
-
Quite weighty

The big advantage of cordless strimmers is that there’s no cable to limit your movement or accidentally cut. The 36V fade-free Lithium Ion battery in this Black & Decker can cut up to 3,750 linear metres before needing a recharge. The 30cm cutting swathe is very decent, too, while the telescopic tube means it’s easy to find a comfortable hand position. 

This model has two operating modes: ECO for normal cutting and TURBO for maximum power of up to 8,500rpm. At 3.5kg it’s not especially light for a battery-powered strimmer but, if you’re been disappointed by cordless models in the past, we think you’ll be pleasantly surprised by how long this one lasts between charges.

Cord is only 2m long

If you don’t have a huge garden to trim or much money at all to spend on a unit, this corded Bosch strimmer is a strong choice: the 23cm cutting area isn’t as big as some rivals, but neither is the price tag. It weighs just 2.1kg, too, meaning it is easy to handle.

The spool is a single line job with semi-automatic feeding and it’s fine for grass up to 15cm high, although the lack of a heavy-duty option means that’s about the only growing thing you’ll want to tackle with this unit.

It is a corded strimmer as you would expect from this price point, but you get a six metre cable in the box so you've got some reach. For small gardens where all you want to do is trim grass, this is a decent fit. Bosch is also an incredibly popular and reliable brand so you can feel confident that it will last a while.

Some of us dream of freedom. Freedom from the shackles of corded strimmers. Freedom from the limits of battery technology. Freedom to cut whatever we damn well please, wherever we want to damn well do it, while making a whole bunch of noise. And that means we dream of petrol-powered strimmers like this excellent all-rounder from Stihl, the company of choice among pros. 

The Stihl FS40 is equipped with a 27cc two-stroke petrol engine, a 0.34-litre fuel tank and a short, easy-pull starting cord. When it comes to serious hacking back of all lengths of grass for long periods of time, this 38cm petrol beast is a perfect choice. 

Being petrol driven, you can use it anywhere and, being of Stihl origin, you can be sure it’ll run reliably for many years. Tip: use Aspen 2 two-stroke fuel mix for extra reliability, better performance and fewer emissions.
