I have one of his Tuck Clips for a J frame. It is as solid as it looks, fits the gun well and has just enough grip to keep the gun in the holster unless you want to take it out. I think its quality is at least equal to its price, and it was delivered in the time frame promised. The offset tuckable clip makes it as thin as an all leather IWB tuckable can get, which was one of the principal factors in my choice. I feel that I absolutely got my money's worth.
That said, I found that with MY gun on MY belt and MY body and daily routine, the single belt clip design let the gun/holster tip forward (and down) over the course of the day. It didn't get uncomfortable, but I didn't like the idea of the gun moving around like that. So I went back to a locally made hybrid (kydex & leather) design with two clips for my daily carry. It ain't elegant, it's not even pretty, but for ME it's more functional. It also turns out to be thinner, overall, than any all-leather design I've seen. With my slowly expanding waist, that's a plus.
