The light weight is convenient for small jobs around the house. I had several problems. Several times the drill stopped turning while drilling. It still sounded the way it was. I seem to have found that between 1 and 2 the switch can accidentally slip off and not latch. Today I had it turned on but it just broke into the hole. I drilled straight into 2x4. My same size racquet from another set worked perfectly in the same application. I suspect it is of low quality. The engine just stopped responding today. I've never had such a sudden stop. But I put the battery in the charger for a while and it came back. It's not very good compared to my similarly equipped Tacklife, which I've never had any problems with.
