It's heavy duty and there doesn't appear to be any defects. The knurling leaves a bit to be desired, but....it's a rotating handle and it does what it says it does.
This was one of the first things I bought for my gym in 2019 and it has held up extremely well. I have well over 1000 lbs of weight stored on it, so don't be scared by the 2x3. I wish Rogue made more 2x3 attachments but there are plenty of other manufacturers out there who do.
These are well made and I like them, but I like the dual ply sandbags from Cerberus just a bit more. The liners on these will wear over time and sand will eventually come out, but you'll get a lot of use out of them before that happens. Also, folks tend to use duct tape on the top of the bags versus the 1" webbing for a reason.
