Worth noting that the lever itself is only a yr warranty and sounds like a lot of guys get several yrs at least out of em. The prong is under the belts warranty though - lifetime, at least for suede. Leather is only lifetime provided you oil it routinely. I love my suede though and it's cheaper so can't go wrong there. I don't mind buying a couple new levers down the road but it's significantly pricier than a single prong in the long run.
No experience there personally to comment, but I can say that this belt is serious and legit; it's hard to me to imagine anything like happening with something so sturdy even if mine were pronged. I just love how fast a lever is on and off. Flip latch, get tight/take air, lift, unlatch. Almost feels like cheating.
Ordered directly from titan support systems since I wanted maroon and to specify the size. 110 shipped and took 7 weeks. Buddy got one of the ready to order blue 10mm Longhorn Leverbelts I believe from Lifting Large because it was like 80ish shipped I THINK. Def cheaper and a bit quicker as long as you're happy with black, blue or blood red and don't need embroidering or anything special. But his still took like 5-6 weeks to show up.
I use a 6.5 single prong powerlifting belt and it works great. As far as brand I dont think that makes a huge difference.
I haven't seen any other 6.5 mm belts besides that one
