It's too early to tell about the durability and wear of the belt, but so far, I love the way it operates. I've only had it for a couple of days, but I love the look. I was also a little concerned that the buckle might be too dark but it's just the way that the light was reflecting on the pattern in the picture. It's basically the same color as the rest of the hardware (light gunmetal) with a mild graphic pattern.
The ratchet looks like it works as advertised to be released with a single hand and the adjustments are easy enough to fine tune.
As for the sizing, I've been buying 42" belts. This one (36" - 42") is about 1/2" longer than a couple of them and about an 1" shorter than a couple of others (all of which are marked 42) -- so I'd say you can buy with sizing confidence. On me it looks like a perfect fit and I appreciate the not quite infinite adjustments because of the ratchet mechanism. I didn't have to cut mine down, but I would say for anyone smaller than the 42" size you'd probably cut it down. The instructions look easy enough to do, but, again, I didn't need to cut mine down.
I bought it in golf white because I'm replacing another white belt and 3 days in it still looks great. If it wears well, I will probably replace the rest of my belts (dress and casual) in time with this brand. I really am loving the look and the ratchet mechanism is cool, but not just a gimmick, it works practically. Price was a factor in my decision to try this out, and it didn't hurt my feelings that it wasn't very expensive, but having tried it, I would pay more (again, depending on how it wears).
If it wears out prematurely, I'll update the review, but in the absence of that, I'd say give this a go.
