Formerly on iPhone 5, I passed on this Wiko Since 3 days: what happiness! I doubted the quality given the very low price of the device, but for now I feel like on a mobile quality. I wanted a big screen mobile with expandable memory but especially with a good battery! 2 days in normal use (social networks, some pictures, messages, calls)! The picture quality is pretty good (certainly not as good as on the iPhone, but it defends itself! ^^). Quality of the screen: no complaints. Very fluid, no beug. I preferred to buy in stores rather than on the net given what I've read about the customer service brand, my device is guaranteed for 2 years store ->: D Honestly, for the price it is just amazing! If you are not a gamer or a pro in the photo and that you are just looking for a good quality phone that holds more than one day without recharging: go for it! Now only time will tell me if this mobile is built to last;)
