I am very disappointed in this product. No variable speed making it difficult to use. I bought this cordless screw driver to get more torque than some "cheap-os" I have. It turns out when even when you begin to load it, the thing "slips". Heck I'd rather use my "cheap-os". I would not recommend this product. It is just too frustrating to use and you'd be better off with just about any other kind of cordless screw driver.
