For how inexpensive this thing is, it is very well built. I left mine at the local Y for nearly a year because several friends were also using it for weighted dips and pullups. It got a LOT of use but none of the stitching has come out and, other than getting a bit dirty and chalky, it doesn't look any the worse for wear so far. The cordura straps on each side that hold the D rings have gotten a bit smashed and now the D rings spin freely, but that hasn't affected function at all. I've had three 45lb plates hanging on it for heavy dips and it remains stable and comfortable. I haven't felt any need to change the chain or carabiners, they are working just fine. Folds up compactly and tucks into my gym bag easily. This is a no-brainer purchase if you're looking to increase the weight on your dips and pullups.
