Junk. I'm a person who takes 1 star reviews with a grain of salt, but in this case I feel it my duty to spare other people the experience I had. It's so disheartening when the "tool" is of such poor quality. This device replaced a similar angle drive that failed after 3 years of use. Isn't it strange that these tools seem to be made from the same molds and parts? One would think that the quality would be at least similar. After receiving it, I put it in my tool box and was unable to use the device until the return period had expired. When installing the first #8 x 2" (regular/small) screw with a DRILL (not an impact wrench), it started cracking and grinding its teeth. The fourth or sixth screw was scrap. All the gear teeth are broken and I am left with work unfinished, I need to find a replacement. Of course you can say: You get what you pay for. But the last physically identical device worked fine for years, so I tried again with decent reviews that gave me hope. No longer. replaced with an expensive pad from a retail store. Stay healthy and best regards.
