I bought this for our little home gym. The weights are accurate and comfortable to use. I did read reviews that said the plastic stand came broken for a lot of customers. I did not personally have this issue so maybe they upgraded their packaging. I can say it is a little flimsy but it works for me just fine and I don't plan on returning.
