    Miss Olaves

    Great garden trimmer. Only have a small lawn so this just stores under my stairs and I can push it along like my vacuum cleaner! Highly Recommend!

    I was hopeful but a bit sceptical about this strimmer as we have a boggy, mossy, sloping garden where a normal petrol strimmer works but is heavy going. This little strimmer certainly works hard. Easy and light to manage which is a bonus in my ‘twilight’ years. I managed to cut a large area of our garden before the battery (and I) gave out. I would definitely recommend it. An easy five stars.

So What Makes Us Different?

In developing the TriMower '2-in-1' Mow-Trim we realised the difference between a bad cut - and a great cut - is a uniformed cutting length...

Previously very tricky to do with a grass trimmer!

So we invented the Guard Glider, to simply clip on to all our Trimmers, to help glide over your lawn following the contours of the ground allowing an easy, perfect cut - SIMPLY!
