"Bought this bare to go along with the hitachi drill also on offer as the drill had an extra battery which i could chuck into this. I've thrown all sorts at it and had no problems at all. Battery seems to last well in fact one feature I do like is the fact the thing will just die when the battery is too low, rather then slowly grinding down to a halt. I'm not trade and to be honest I don't know anyone with an impact driver. I've since recommended purchasing one to several people. Knocks spots of using the drill as a screw driver. My only issue is it does seem to kill bits. It may be me not getting the driver quite square, but it totally shattered several Hitachi bits I bought at the same time."
