The price of the SBD belt seems to have gone up since I bought mine, but if someone nicked it or I lost it, I’d buy another one. You get all the benefits of both a prong and lever belt in one without the shortcomings. Other than the price, the only negative is the work it takes to break it in and that the edges dig into me a when I go tighter for heavy singles to the point of leaving questionable marks, but I’m not packing much padding. Someone I know cracked a rib on a 1RM squat doing it extra tight the first time she used it, it is vice-like, unforgiving and feels like it’ll last as long as you need it to.
I don’t trust the SS one as much - as well as being softer, prone to having the screws loosen over time and undergoing a slow process of decomposition, the original buckle fell to pieces and I had to send the lifetime guaranteed Riot buckle back once as the pin fell out of the lever mechanism mid-set. It still works fine for the job it’s intended to do but I don’t fully trust it now. I’m sure others have never had a problem with theirs though and maybe I just got a dud.
