Black and Decker 36V Lithium Ion Strimmer UK Review 

 July 9, 2017

By  Enda

The Black & Decker GLC3630L20 model, is one of the highest selling strimmers, on the UK market right now. It is powered by a 36 volt lithium-ion battery, that lasts for ages and is really very powerful indeed.

It is not cheap with an RRP of £169.99. Shop around though as you can get this online for around £130. Buyers do rate this model highly.  On average it has achieved and maintained a rating of 4.6 out of 5 stars. If you like the idea of cordless free strimming, then this is a very good choice.

This one is ideal for those with medium to large sized gardens, and can easily deal with tough weeds, or long grass.

I am someone who enjoys a little gardening. Now I am not someone who spend hours in the garden, but I do like both my front and back gardens to look really nice. Well kept lawns, neatly trimmed hedges, and borders filled with plants, make a huge difference, to how your property looks.
