It was delivered yesterday. I can only comment on weight now. Both dumbell are supposed to be 3 kg but both have different weight. 3.1 and 2.9 kg. I will update about quality after some days of use. On a first glance it seems something loose as sand in filled in plastic covers.
One of the dumbell was broken from inside , I could feel & hear something broken since I started using it late I couldn’t change. I am using it & is serving the purpose but receiving a broken product is not that great an experience.
