Hi guy’s
Emprsent DZO9 samartwatch is good in looks.as it it is chinese so it doesn’t work longer.some time sim doesn’t work in it.its battery backup is poor.the watch shows whatsapp, facebook, twitter but it doesn’t work. Its sound quality is bad .there is no audio jack in watch so while talking with soneone we have to hold it near ear so that look so awkward.i tell you my real experiene that I went out of station for 13-14 days and after coming back when I start my watch then firsty it start and then it switch off and now it is not working.
