What is the opinion of Reddit about the
RDX Weight Lifting Belt Powerlifting, Approved By IPL and USPA, 10mm Thick 4″ Leather Lumbar Back Support, Lever Buckle Gym Strength Training Equipment, Bodybuilding Deadlifts Squats Workout Men Women?

I prefer lever belts personally and just picked up some cheap one on Amazon. Routinely deadlift 500+ish on it without issues.

I use this RDX lever belt I bought on Amazon.

Don’t have anything really to compare to, but the price is right (50 bucks) and it’s been sturdy so far. Got through about 9 months of training and two strongman contests so far, no issues.
