I suspect most of the 5 star reviews here have been left by people without advanced levels of strength who are using less than +40kg weights on this. When I got to pull ups with +33kg the buttons on the sides popped off, so I replaced them with bolts and washers and continued on fine for another year or so. Then when I got stronger then buttons on the back popped off. These buttons are made of extremely thin, cheap metal (like almost all belts out there). After I replaced these with bolts as well, I got strong enough to do pull ups with +55kg, then the leather ripped. The low rating is entirely for the complete lack of regard for safety on the myprotein sales team. If you say this thing is rated to 100kg you had better be sure that it actually is/that you're testing it properly. I had the pleasure of having my instep crushed by 55kg of weight which made walking an absolute delight for about 8 weeks. I'm leaving this review to tell people to avoid this belt if you ever hope to attach big weights to it for your own safety. One thing this belt is great for is comfort which is why I haven't given it one star. To sum up, fine for weaker lifters, completely wrong for strong lifters.

its great for my weighted dips and pullups and much more if you are creative It withstands very heavy weight, its sturdy, easy to use and very comfortable. honestely there is nothing bad I can say about this great product, would recommend for weighted calithenics

Great dipping belt to add weights to your pull ups or dips. No any discomfort what so ever when wearing it with weights. Built quality and material quality is good. I have not tried more weights but it feels like it can hold heavy weights as well

Had this belt for over a year now and it still feels pretty much brand new. Its' perfect to add weight when you're doing pull ups and dips and remains comfortable with the added weight. Money well spent!

This Product is apparently rated to 100kg but the leather was starting to tear at 65, and became unusably torn at 80

This belt was ok for a short period of time, however one of the fixings that’s holds the leather together popper out under a load of just 45kg. As others have said, there is no chance of getting close to 100kg as the chain is too short. Probably worth a buy if you won’t ever need to put more than 40kg on.
