Wow! I weigh 450 pounds and thought this belt wouldn't hold up (ba dum tiss). I've torn those cheap ratchet straps so bad I'm tired of wasting money. I absolutely LOVE this belt! You think the plastic buckle will break, but it's made of very durable plastic, which is great. I think it's ABS but I could be wrong. I saw a youtube video reviewing the belt and they told me not to buy it because the quality is lower. But I didn't see that the belt had deformed a bit over time. They also said the belt would roll and I haven't seen that yet. It is very sturdy and very durable! I don't buy belts anywhere anymore! I want to check out their other belts and see what I can get. When I receive them I will write more reviews! Thank you Thomas Bates!
