Great drill. Super engineering. i got the one with the larger capacity batteries and they have a really long run time. ANd the drill is designed so that the weight is not a problem. Very well designed and engineered. Pwerful and the easy to use chuck is absolutely super. I like the way you can check on the battery capacity by pushing a button on the battery. THe charger is nice, has a built in handle and it charges really fast. This is a powerful tool, and better than the others I have used in the past.

I've owned this drill for a little over 3 months, and overall I am not impressed. I've used a Milwaukee 28v too, and I think that it is a better overall drill. I'll start with the design flaws. Plastic outer covering on the chuck. While drilling in tight quarters where I couldn't see too well the chuck was rubbing against a cinder block and got all chewed up, then when I went to remove the bit form the chuck the chewed up fragments of plastic sliced up my hand. 2ND the switch for high torque to high speed should switch in the opposite direction (like the milwaukee 28v) while drilling along side of studs or floor joists the switch is easy to hit, therefore disengaging the drill into a neutral or between gears position, very frustrating. Lastly I was drilling an 1 1/4in hole the other day when i hit a nail, but thanks to the handle I was able to control the drill but apparently the drill can't handle its own torque because the chuck literally snapped right off. I got this drill in a combo and I love the sawzall (unbelievably fast and powerful) and the circular saw rocks. The batteries are great as well and last very long. I admit that I am hard on my drills, but I couldn't help but laugh while holding my drill in two pieces while reaing the brute tough logo on it.

This is a wonderful drill. The first drill that always ran true (no wobble in the bit during use)! As light as my old 18v Ridgid hammer drill. Incredible power! The best drill I've ever owned! Bosch has also created a wonderful case for the drill. This is about the same price as many 18-volt hammer drills, is better quality than nearly any other cordless hammer drill, light weight, more power and Bosch quality! What's not to like? I resoundingly recommend this drill!

This drill is amazingly powerful. The battery is the heart of the system. The newer Lithium Ion batteries, such as this one, have no memory effect and can be charged early or at the dead state. This battery rocks! Lots of power all the way up to its long long end of charge.
