I ordered these weights for a weight training program that I am doing. I opted for these because the price of Selectechs was so very much higher. As one reviewer mentioned, they do 'clank' but that doesn't bother me. I have a issue with switching from one weight poundage to another with ease. The lever seems to 'stick' and not move very freely. Also, when picking up the weights from the racks, sometimes the remaining weights shift and you have to move them back to their proper position. I am not displeased with the weights but would recommend to save your pennies for the set that is more expensive. If this is what you have to spend, these aren't bad for the price.
I do like that they have their own holding rack. That comes in handy. And it is included and not a seperate purchase. I also like that you can select increments in 2.5 pounds and that both ends of a dumbell don't have to have the same weights.
So overall, they'll do. Not estatic, not disgruntled. Just middle of the road.
