Summary: I bought this drill because of the Consumer Reports top pick recommendation. Typically I like to purchase Bosch or other high quality tools. I don't mind paying if the quality and features are there. This drill has a few issues: Location position of reversing switch is not good. I have accidentally switched it several times by accident. Drill bits don't center easily in the chuck. I often have to remove and reinstall non centered bits.
Summary: I would have given 5 stars solely on it's excellent performance. It's relatively light, strong torque, excellent batteries and retains charge for a good long time. I am glad I got this drill beyond any others. However, there are a couple fo things that do bug me about it. It doesn't come with any accessories/bits. There is only one place to store a bit and you have to take the battery out to access this area and will only hold one bit.
Summary: I purchased the original 3.0 amp-hour 15.6 drill in winter 1999. The drill has always perfomed flawlessly and easliy had the best run time in comparison to 12 volt Makita's and 14.4 volt Dewalts I had used previously. I built two small boats out of white oak with this drill (all drilling and screwing) as my only drill. This included numerous 2 1/2" hole sawing through 3/4" particle board temporary framing. The drill is awesome. My "but" comes with the battery life.
