The article comes in excellent condition and without damage, the external characteristics completely satisfactory, however I have had a lot of difficulty activating the Bluetooth of the watch so I can set it up and the instructive though it comes in several languages has not been very helpful. So far I have not been able to fully activate and configure the clock functions. Hi, the smart watch works perfectly, he had had connectivity problems but through communication with the seller solve it, complies with the characteristics indicated in the sales announcement, however, I must point out that the duration of the stack is very low compared to my expectations
