The only reason I only give this 4 stars is that more size options would be great.
If you ever work on anything that has screws in hard to get areas and are sick of having those screws fall off of your driver to play hide and seek with you, buy this tool! It will physically hold many screws to the tool until you are able to get the screws started. I work with a lot of tiny screws, and this tool saves me a lot of stress chasing down one of a kind screws that fall off of normal screwdrivers.
Many people will use a magnetic tool for this, but I deal with a lot of stainless, brass & plastic screws, which are not magnetic.
