I have bought this product and using it from last 5months and as after using for days now I am getting a problem that is it is not working properly.everytime its display gets off and search for network.its touch is totally unbelievable because its touch doesnt work at a point of any edges.It is too bulky and price is also too high as compared to others and afterall the charging is nit good because it has no battery backup.Its band is too slippery and gets sweatng in more use.It is not a average product as compared to others.
