Review on URBNFit Gymnastic Rings - Non-Slip Olympic Rings with Adjustable Straps for Crossfit, Bodyweight Workouts, and Strength Training at Home or Gym by Brandon Show

Buckles are not suitable for this set. I was using the rings for about 3 weeks (training with them about 3 times a week) when one of the buckles started slipping. I didn't think about it too much because if I put the buckle on and then pull the tab it will lock itself so it won't be too much inconvenience. Well, over time it lessened, it was scary, and then the other buckle started to work the same way. I started putting a stack of pillows under me, just in case. They kept sliding. After about 2 months of using these things, both buckles will slip free, making them unusable. I'm certainly not a buckle expert, but look for belts with buckles that have better prongs, better ratings, or something like that. Whatever you're looking for in a buckle, this isn't it. I'm not quite McBeefy at 6ft 180lbs either.
