First of positive, the dumbbells are easy to put on and they fit comfortably in your hand.
Furthermore, the advertised not roll the dumbbells, I can confirm that.
What I am very, really is very disturbing the size of the weights.
They are really quite fat and happy for 10KG per dumbbell ...
This affects just too big and clunky and you might think it would 30KG dumbbells instead of 10th
Furthermore, I find the quality of weight plates not so good.
All in all there are solid weights that are easy to build and are well suited to home to train a bit.
However, I would not buy me one more time but would rather invest 10 Euros more for smaller weights with the same weight.
Who has a lot of space and a point that defines the dumbbells can not roll away, I recommend the dumbbells quiet, otherwise you will look better to continue.
