Happy with my purchase. The battery lasts a long time but the load is longer than what I'm used to with my xperia Z2 phone, which is normal in fact. The wide edges are actually handy to hold the device. For me it was not necessary to take the tablet 4g since I can connect to my phone turned into a WiFi access point. I add that it is nowhere said that this tablet has an infrared transmitter. Here though I'm using it as a remote for my Samsung TV (not WiFi) but for my Samsung mini chain (also) it does not work, but it is old.
