Super purchase. Highly recommended. 1

Excellent product.
Received 1 days after order. Tested immediately. It takes super well on the same arm with sweat ... The small dot rubber in the back are for something. The touchscreen responds quite well together after launching the app + music I do affects over.
Too bad there have no cable wrap but I found a little trick for that.
Anyway, super happy with my purchase used two already out. It remains to see how you hold it in the rain.
Ps: I do not put 5 stars because I assumed that everything can be improved but prowler at the top.
