Summary :   Follow the instructions and this tool works great.

Excellent and intelligent design and build quality for the money and it's put together here in the states. That just makes me happy. This tool will accurately sharpen bits from 3/32 to 1/2" if you follow the instructions, especially the fine points about the smaller bits. Being able to split points and create self centering bits is great for all hand held drill uses. I look forward to finding a dull bit smaller than 3/32. The alignment step is critical and the video helps to clarify that.
