Review: Buying this is the greatest regret I've had in the $750 of tools I've purchased for this hobby. Rolls off the desk, all three came with rusty barrels, the hex key is made of rubber putty, the locking pin isn't held with LocTite or anything, the cap doesn't go anywhere, the cap has lots of threads meaning you have to leave tools uncapped for faster access, and did I mention this costs $10 and I bought three? Also the aluminum is low-density, the machining quality is very bad, and the finish is all lumpy.
