The weights are fine, but the description clearly states they are 10 pounds each. This is not true - they are 5 pounds each. The description also says they are made in the USA - also not true. The box says they are made in China. Those are the two reasons I chose these weights and both are untrue.
It's heavy. Which is what it's supposed to do. And you can adjust the weights. It's a bit hard to get the adjustable weights into their pouches (getting them out is easy though). Hence I docked a star. But as far as their main job, which is to be heavy, they do that excellently.
