Garden Tool Reviews

String trimmers are becoming an integral part of home maintenance. These garden tools have  revolutionised what used to be an arduous and dangerous chore - trimming weeds and long grass with manual tools.

Other names used to refer to them are ‘weed eaters’ and ‘weed whackers’.

Here are the 5 most popular string trimmers on the market today:​

#1 - Black+Decker LST300 12" Cordless Trimmer/Edger

BLACK+DECKER LST300 Weed Whacker

Weighing in at an impressively light 6.75lb complete with battery (almost as light as some corded models), the Black+Decker LST300 is our pick.

The manufacturer claims this model has 33% more run time than their previous version (partly down to an improved battery pack). Users are reporting 1 hour+ run times from a single charge (this will depend on the thickness of the weeds & grass you're trimming)

With this trimmer/edger you can tackle the toughest overgrowth & the heaviest weeds.

If you have an older 2-stroke gas trimmer you're looking to replace, this model should do everything your old trimmer does and more. You'll appreciate the much lower weight, quietness and ease of starting. The lack of maintenance required is an added bonus.

Like most modern electric trimmers, this one will easily convert from a trimmer to an edger.

One slight niggle - it has been reported that the replacement line spools can be fiddly to replace.

Overall, this is great value.

Black+Decker back this trimmer with a 2-year warranty for home use.
