Curious about the GTech grass trimmer and if it’s worth the money?
You’re in the right place.
This in-depth, honest review has everything you need to know about GTech grass trimmers. Both the new ST20 and the old ST05 and I reveal some secrets you may not know…
The GTech ST20 Grass Trimmer is a British made, premium quality grass trimmer, strimmer and edge cutter.
ST20 vs ST05
The GTech strimmer ST05 was also called the “GTech rapid blade pro” and had a 14.4v battery. The new ST20 has a more powerful 18v lithium-ion GTech strimmer battery.
Designed for improved efficiency, it lasts longer and delivers a more consistent power output, resulting in a far superior cut to your lawn.
Here are some major benefits:
- Impressive design and build quality
- Lightweight, only 1.75kg
Easy to Use
- Maneuverable and easy to handle
- Doubles as an edge trimmer
- Reassuringly British built
- FREE GTech strimmer blades for life!
- Durable 18V lithium-ion battery
- 30 min use from a 4 hour charge
Here’s the thing…

Is it Right for you?
We love this grass trimmer and lawn edger from GTech so we’d say “yes, it is probably right for you”.
However, it does depend how you intend to use it and what you use it for…
This cordless, electric tool is designed for keeping the lawn tidy and general use, where you do not need to use it for extended periods. If you’re a professional lawn keeper, this isn’t for you.
You can tell from the hundreds of happy customers that this tool does a great job, is really convenient and easy to use.
It’s ideal if you want to quickly neaten up the lawn edges, around trees and obstacles in the garden. I can highly recommend this product and am sure you won’t be disappointed.
