Just before Xmas last year I treated myself to a Makita DF010DSE 7.2v driver
Took it into the hire company last Tuesday afternoon, they called today to say it was ready. To my surprise Makita replaced it with a brand new one! Not only that, I'd just returned the tool & 1 battery. They sent a complete new one, 2 x batteries, charger, case, bits etc.
Can't argue with after sales service like that.
