The Black & Decker GLC3630L cordless grass trimmer looks a pretty impressive machine.
It has featured in a couple of national newspaper features. In February 2014 The Telegraph named it one of “The top 10 garden trimmers“, and The Independent listed it as one of “The 10 best garden power tools“. in April 2013.
This strimmer is powered by a powerful 36 volt 2Ah rechargeable lithium battery.
Tooled-up are currently including a complimentary Black & Decker A6481 Replacement Spool & 10 Metre Line when you purchase the Black & Decker GLC3630L cordless grass trimmer from their web site.
The video below demonstrates the features of the Black and Decker GLC3630L and shows it in use.
