Band pin on the cheap side causing it to fall off. Other than that good for the moneyGreat watch, super features, but alas! the instructions are typed in a microscopic-sized font, so it was difficult to set up, turn on, etc.Note that, although a spiffy watch to wear with cool features, it is constantly reading your vitals, so it doesn't hold the charge for long.BellosThis watch had a great look and weight. But that was it. Either it would not give no notifications or too many. When I plugged it in, the vibration would happen every 5 seconds it was charging to notify you it was charging. There was no way to turn down the vibration level and the interface was hard to use. Coming from a samsung, this was not adequate or and equivalent.This is my first smart watch so I had some technical issues getting the functions to work properly but in the end found this watch to be pretty awesome for the price point. The case of the watch is decently made and presents well, the band is okay for being a budget look a like. The features all work and I hope it lasts a while because I really like it. All in all I would recommend this smart watch to a friend. The dial faces are interchangeable and comes preloaded with blue, green and black submariner style dials as well as a rose gold and a silver yacht master style dials. There are hundreds of other free dials that you can upload at will as well.Only one week, so i’m still open-minded, but seems like an excellent purchase. The fact that this ewatch is in a jewelry type case is a big plus. Functions seem reasonably accurate. Would recommend. Give it a 5+ (so far).Battery Life drain is significantly fast. Went from 100% to 70% in about an hourUnable to receive SMS notificationsUnable to play music (App says call only version)Included instructions are too small to read and cannot find a PDF version onlineBlood pressure reading is worthless (as I expected it would be), but makes other vitals suspectVery nice watch, high quality. Watch itself seems great but the app to control it and make changes needs lots of work.Después de 5 horas pude conectarlo. Una pestaña, casi invisible, era la clave. No se conecta desde blue sino de la aplicación y es casi imposible adivinar, al menos para mi.Es un Reloj de buena Calidad, estético y funcional, fácil de manejar y muchas caratulas qué se pueden combinar
