I had one for a couple of years until the USB connector fell out and I couldn't charge it. I thought about buying the same product again. After doing more research I settled on a second one, exactly the same as the first. I love it. BUT. This second one, just a few months later, had the same problem. The USB port fell out and I couldn't charge it. i love power The size. Feeling. It was ideal for small jobs. But I hate to say: I do not recommend this product. I think it would be better with a different type of charging port. So I bought another brand with a different charging port and hope it works. BTW: I have a few other more powerful cordless drills, including a battery-powered Dewalt screwdriver. These units have served for several years without any problems.
