Over the years I have owned many rechargeable drills and never that happy with the battery life especially when the batteries would need to be replaced every year. I received 2 of these drills as gifts a couple years ago and really like them and for the first time the batteries have lasted 2 years and still going strong. The batteries recharge quickly and hold the charge well while working with the drill. I have used the drill with hole saws which put a strain on the drill with no problem. Recently used the drill as a screw gun and hung sheet rock with it, we got 3 hours use out of each battery, plenty long enough to finish the job. I bought 2 more of the drills to give my adult daughters to have in their homes for when I„¢¯m there doing remodel work. The light weight and smaller size compared to the 18 or 20 volt drills make them good for the girls to work with as well.
