I don't really have the criteria to really evaluate this product because it is the first clasp of this type I've experienced, but I have to say it feels great; it is very solid and secure. It feels serious put together in the DeBeer sports leather strap....it works AWESOME for me!!
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 like it alot. Never knew this kind of buckle existed. Placed it on a blue suede band from the same company, Fluco. Because I live in NC and it's summer, I don't wear a lot of leather bands till fall but so far taking it on and off. However, my experience, sides of leather bands can become worn as you tighten the buckle, especially with darker leathers like blues and blacks. I can see how it will preserve the sides of the band better than a standard buckle.
Nice deployant that will accommodate a thicker strap.
I just received them. So far, Excellent. For some reason, deployant clasp fit me much better. The build of these seem to be solid.
