If this drill were fully functional. I would rate it better. First, it came with an LED backlight that didn't work at all. - what is important to me. - Second, when I used the drill, the chuck immediately unscrewed from the drill. — I know they wanted me to send a replacement drill before I wrote this review, but I paid. good money for a refurbished drill from Amazon. & it should never have come to me as it did. And anyone wondering whether to buy this remanufactured drill from Amazon deserves to know the truth! I kept the drill because I don't have time to return it. I am too busy. They should send a special representative to take care of it. Or pay me for wasted time. Lord knows I pay them good bucks for Revain Prime every month. Which isn't even worth it in the long run. I'm tempted to go back and use ebay.
