The tubular picks themselves are well-machined and operate smoothly. The knurling on the handles is very nice, and the tools feel very nice in the hand. The picks include removable tension pins.

I had only a few tubular locks to hand, but each was quickly opened.

The acrylic lock included is very nice for demonstrating the principle of operation of tubular locks, includes its own case, and looks very nice. It's utility beyond that is somewhat limited.

This set has indexing pins unlike the set without the practice lock. These work very well, much better than my set from another manufacturer.

One pick had trouble taking an indexing pin without opening it up with a 1mm drill bit (by hand, not drilling). Must have had some edge at the top of the drilled hole I guess.

Practice lock is of awfull quality. It is very rough. It was barely able to open with the key supplied and after turning a full turn it does not open even with a key. Never wanted this kit for the lock anyway, I wanted this because it has indexing pins.
