This is a great kit especially if you change scopes or buy new "toys often. I have to say the two times I have used it so far I haven't needed to lap any rings however it offers great piece of mind and the level while a little fiddly is easier than the manual kit I had previously. There are many parts of this kit you may not use very often but again the piece of mind is worth it
Pros: piece of mind
Cons: limited bit range
