Other faults:
- Very dirty dumbbells (sand coming out if it is not carefully placed on the ground), practicing in a garage or terrace
- Plastic dumbbells smells terrible (after an hour of manipulation, it becomes a problem: /)
Positives:
- Not very big, compared to the usual muscu rooms dumbbells
- It muscle :-)
Otherwise, it's just normal to have this quality for this price. I'm still happy long as it gets the job done correctly.
