What size diameter and thickness did you buy?

Echoing what others are saying. Go for it.

Glidelock-style clasp for less than $40 are really bad quality. And your suggestions for improvement on the San Martin clasp are pretty much already implemented on their newer version which @Waybe_6 posted above.

Then what clasp would you recommend that is cheaper, shorter and offers more adjustment?

San Martin’s clasp for $40 is solid. It works the same as an Omega.
