Among the qualities, crystal clear packaging of course (but it is doubtful make you want to keep long this package)
Difficult to know what materials are these dumbbells because the weights are covered with plastic, which is a very good idea for two reasons: First contact is never cold, which is nice, and also on edge each weight is a small flattened area, allowing (provided you do a bit careful, it does not jump to the eyes inevitably) ask these dumbbells without that they can roll on the floor then. Great idea!
Two drawbacks, however:
- The diameter of the weight is, for my taste, too. I would have preferred weight may be thicker, but less great, it takes poins space, and it makes certain movements (flexion fuller etc)
- Screwing system for attaching weights: Does not seem super efficient, so we tend to squeeze a little more strongly. And when we shook heavily, it can be very difficult to loosen these "screw".
Anyway, overall a very good product very easy to use, which is exactly what he should do, and seems reliable, for a price, after all ridiculous.
