らんす 5 First, these dumbbells as an excellent value for the price. If you're a beginner who's looking for a low investment option for weightlifting at home, I think this is a great option to start with.That being said, there are 2 things to note:1) The smell: a lot of reviews talk about this, and it is definitely a thing. The weights and handles are gonna smell weird for a while after you open them up, and that smell will get on your hands as you use them. However, a good hand washing will get rid of it after your workout.2) Screw locks: these dumbbells use screw-type locks for the weights. They hold they weights just fine, but they do make it annoying to change the weights. Kind of unavoidable for a low-cost option, but definitely something to be aware of.
