Adrian Zamfir, 22/09/2021

Good last long

Mr Stefan Ozarchievici, 13/06/2021

Failed after 14 months and minimal use. Dewalt only provide one years warranty (USA have three years) and their ‘repair dealer’ they directed me to, cannot repair batteries, so that phone call resulted in my being fobbed off. Very disappointing after £100 spent. Now any extremely expensive paperweight.

Ben Clarkson, 08/04/2021

Good company easy to navigate website competitive prices great delivery times.
