Its totally fake product sell on flipkart by zakk seller from delhi and they sell all types or brand copy products self name as zakk . Zakk u8 smartwatch totally fake I order this at flipkart and when I open its look like a cheap products. Its like a kids watch not a smartwatch. Its bluethooth not working properlly sometimes auto disconnt and some time new device paired problem. I really disappont this seller because they totally sell fake product like bose soundlink mini jbl charge 2 beats headphone and all product they send fake product and name use zakk for only brand name they actually deliver all other populer brand copy items.
