Review title: Great tool, but only when it works
Product review: I am on my second of these impact drivers having had the first one replaced by my local rep due to awful battery life. The replacement unit is just as bad. Even following the mfg's instructions exactly in order to maximize the battery life, the battery discharges rapidly (over just a few weeks) when not in use and I'm left with having to charge it before each use just to get more than a few screws in before it dies. I am an experienced woodworker and hobbyist and own many cordless tools. My 7 yr old 14.4 volt DeWalt with a NiCad battery lasts much longer both in use and storage than this new Panasonic with what should be far superior NiMH batteries. Don't buy it unless you want to be tethered to the charger, in which case a corded tool would be better.
