Summary: It's compact, light weight and well balanced (great ergos), but most certainly doesn't fall short on power. I haven't had it long enough to give and honest opinion on durability but if it's anything like my older hitatchi drill...then it'll be great. The value however is kind of a joke if you buy it at full retail price. I never buy any of brand of cordless tool unless it's discounted.
Summary: This product has great power and good balance in the hand. Batteries charge very quickly and maintain there power for a long time. Power control is a great and easy to change. Was able to drive very large fast lag bolts and change power level to accomidate small drywall screws with ease.
