I can't comment on longevity as I use it on a hobby basis but for the crystal work i have done so far it has worked very well and I don't have to worry about cracking or improperly seating it due to lack of grip strength.
It is a little bigger than what I thought but rugged aluminum construction
The finishes are good and it is well made. there is minimum play with the shaft which allows better alignment of the crystal to the watch case during installation. not cheap but reasonable price.
