Quality Judgement Tips:
Weight: compare the actual weight and the marked weight; the error range is generally within 3 %.
Smell: the more inferior recycled materials there are, the heavier the smell will be.
Finish: the surface of a good dumbbell is smooth and flat with fine seams. In addition, the thicker the surface coating or rubber layer, the more durable it is.
