Phone in hand for 1 year, no serious problems to report or bug that led to removing the battery. Fluid and intuitive, made regular update of Windows 8 (.1). 512MB of RAM a bit limited for games (but hey, a GSM is not a console) otherwise perfect for the rest of the phone. For regular use, the battery takes several days provided they do not abuse the Internet, which is okay for a smartphone.
Very plastic finish, household: my protection used:
For the price this is a very good mobile phone, I recommend.
