These bits are, as expected, fantastic. I use them on a mini router and they cut through stock with no problem. i really love her It's a shame, however, that, as many have pointed out, they're almost impossible to get out of the case. They are too tight in their mounts. I wouldn't mind other tools/bits, but since these things are razor sharp, it's really dangerous to get them out. To get it out safely without cutting my fingers or damaging the nozzle itself, I have to wrap the nozzle in a towel and gently pull it out with pliers. It's possible that the holes holding the thighs will loosen over time, but at the moment this is far from an ideal situation. At best this product would give 5 stars.
