Initially I was pleased with the speedy delivery. Disappointment soon followed as not even an hour after I put the barbell in, the top ball came off and I swallowed it! I only ever had this happen after months of loosening if I had forgotten to tighten it but this barbell wouldn't even tighten. I thought maybe that's how it was supposed to be, obviously not. I have emailed the company requesting a replacement or refund but have not received a response. Will give updated review if issue is resolved.
