The unit is at first sight really good, the battery is strong and the Android 4.2.2 software is okay. Flaws are the weak resolution which is not quite as speedy processor and the slot covers. To insert the SIM you need the manual because the device is not obvious how to use it properly. The cover for the Micro SD was unfortunately already worn out after the first use and I had to fix it with superglue, because they always came up in his pocket. I have the power as a substitute and for the work, but it's fine, 170 are not exaggerated. So if you need a replacement unit or a cell phone to bridge some time with the Z5 not ill advised.
