Households looking for a handy gadget to help keep their garden in shape may be considering a grass trimmer. Shopping marketplace Yimbly (owned by the Daily Express parent company Reach Plc) has the answer, with the retailer currently offering a £40 discount on the 'easy to use' Thompson & Morgan 20v Grass Trimmer. For a limited time, our readers can get an extra 10% off when they enter the discount code SUMMERDAYS10 at the checkout.

Originally priced at £99.99, this means the gardening tool can be purchased for £53.99. The cordless trimmer can deal with weeds, brambles and grass, and boasts a 90 degree adjustable head. This combined with its extendable length from 95cm to 115cm means the gadget can reach the majority of garden areas with ease.

The Thompson & Morgan 20v Grass Trimmer features an edge guide, a safety guard and a stabilising handle for 'comfortable and safe usage'. It comes with a charger, charging base and a battery, and offers 30 minutes of runtime from a three to five-hour charge. 

Amazon is currently offering a similar Flymo Contour 500E Electric Grass Trimmer and Edger with a 10% discount. Now priced at £62.98, this option has an adjustable, steady handle with a soft grip for greater control and comfortable use.

For shoppers after for a more budget-friendly option, the Bosch EasyGrassCut 23 Grass Strimmer is now on sale at Robert Dyas. This gadget has been reduced from £39.99 to £24.99. It's worth noting, however, that both of these alternatives are not cordless.

There are currently no reviews for the Thompson & Morgan 20v Grass Trimmer on the Yimbly website. Over on Thompson & Morgan's direct website, the gardening tool has received high praise, with every reviewer rating it at least four stars.

One impressed buyer awarded it five stars and wrote: "Great little strimmer. Lightweight and easy to use."

"Does the job brilliantly," commented a second satisfied customer. "Easy to use. Wonderful that it's cordless." Another added: "Does exactly as it says. Very good operation and light to carry."

Someone else explained: "This trimmer is a Godsend. It is light and easy to use. The batteries which power it take only about 30 minutes to recharge, but buying an extra one to use while the other is recharging would be well worth it.

"It is also worth buying some spare blades. The trimmer is good for cutting grass, including trimming lawn edges, and will soon pay for itself in saved gardener's bills in keeping the garden tidy."

However, they did go on to note a downside: "One has to be aware of its limitations, though. Trying to use it where a heavier petrol strimmer is needed to cut thick brambles or tough weeds will dislodge or break its little plastic blade."
