This seems to be a fairly high quality clasp. The mechanism isn't as smooth as others that I've used, which is why I've deducted one star. Other than that, the workmanship seems good. The steel is polished to a very high shine. The reason I chose this clasp is that it advertises a 4mm thickness, and it delivers. I am able to use it with my 4mm-thick 18-mm Hirsch Liberty Strap. It was a tight fit (I actually used a pair of pliers to pull the buckle end through the clasp), but it appears sturdy and is comfortable.
I just received them. So far, Excellent. For some reason, deployant clasp fit me much better. The build of these seem to be solid.
Mine works very smoothly. Not much to say about a product that works well.
This is a well made butterfly clasp. The finishing is beautiful and will accommodate a a variety of fine leather straps. The dual push mechanism is quite secure and easy to use. However, the buckle where the tongue end of the strap goes through does not seem very secure when it snaps into place. But, it could be due to the thinness of my leather strap. Overall, I mostly have positive remarks.
Very comfortable and smooth surface without sharp corners. Originally I purchased another company's less expensive clasp but returned it because of the sharp release push buttons that cut through skin over time. highly recommend.
