Review on MOKENEYE Ultra-Lightweight Titanium Alloy with Plastic Aluminum Design by Adam Krueger

For well under a dollar apiece I have no complaints. Haven't tried them on metal and don't expect to, but for typical wood/plastic joinery use they're great so far. I will never buy non-hex shank bits again. It is very convenient to be able to change drill and screwdriver bits in just a few seconds without changing the chuck hole on the drill. 4 stars for the product itself, 5 stars for the price.
