Have the Cesium 40 now for 4 weeks Gerbrauch. So far there is nothing to complain about. A smartphone with Windows 8.1 for 80 euros, more is not for the price. 2 (normal large) simcards are possible Photo in daylight even useful, LED flash (this ensures unfortunately for some bluish shots) Removable battery, Front camera
I can only recommend, provided you are looking for a Windows Phone :-)
Addendum: In addition, TOP and without problems after 6 months use.
