Decent but a set but the circlips are far from correct. The bit sizes are accurate, but as you can see the rings are so large that the socket head set screws don't even make contact with the bit. The company will definitely have to recreate the collar pack and then include it as I don't have any collars that fit 2 bits and I have 4 collars left. On the plus side, you have additional collars to use with other bits, but this article doesn't work alone when it comes to bits and collars.
