Goods in work for more than a month, there are no problems, I really like it, I regret that I ordered one! Completeness corresponds to the description! Seller recommend! And this goods too!


arrived in good shape, everything as described. One thing it the band annoys me is that it doesn't display caller's name on call notifications. Everything else is super fine.


Product quality. Report data accurately. Water proof. Comfortable.


The product arrived in a little more than 1 month. So put to charge it not called thought was just because was without battery. After days I put new socket and then yes the reifico called. Now works perfectly! The product is very good for the price, worth it!


Arrived descarregavel, yet will test, arrived with 23 business days in my home. Careful not buy this seller, it sends the watches with defects and not return the money and not send another product, it really acts much bad faith.
