Thanks for the review. The chuck seems like a good majority of drills it loses the bit. The power seems consistent and with 2 batteries extras and drill bits it seems like a descent very affordable option. I have a few year old black and decker matrix. It's a impact and the impact comes off and it's a hammer drill. It's a pretty handy do it all tool. The power of b&d is similar to Ryobi. Thanks again I'm subscribing keep up the good work.
