Price / performance is very OK. The workmanship can also be described as good.
Battery life is approximately 8h. at medium screen brightness (about 50% watch movies-and 50% surf)
Decision criteria for the purchase were the (small) native HD resolution, a micro SD card slot, Bluetooth for wireless headset + shipping from Amazon - for trouble Retournierung if not satisfied / techn. Shortage.
3G was not an issue for me since my smartphone "tethering" can. -> Saves cost the tray and the cost of running a simcard for surfing's not at home.
My main applications: watching HD movies on home trainer. For quality playback (video and sound): no jerking, good color rendering / loyalty, excellent sound (via their own headphones, not supplied)
The device itself has everything earned in all 5 *.
One shortcoming is noted, however, for which Lenovo is not to blame, however: Although the Android operating system can read Micro SD cards - provided they have been formatted with FAT32. Files that are larger than 4GB but need the NTFS file system. The support Android default is not. What is so much that as movies over 4GB are not playable.
Only way I know Remedy: root privileges to set up (keyword "SuperSU" in Google Play goals) and with the application "Paragon NTFS" - also available in PlayStore free - mount the computer via Windows NTFS formatted card. Thereafter, for example the VLC Player on the external SD card access (directory "sdcard1" in the app once set up). And finally, it should be mentioned that the contents of the SD card / player of the tray (For example, if files have been transferred to the PC to the SD card) only in File Explorer are visible when the SD card with the application "Paragon NTFS" short "unmounted" and then again "gemounted" is. All in all a tedious thing.
But despite the "small" adversity - a worthwhile purchase!
btw. The bluetooth headset SBH20 Sony "may" incidentally well with the tablet - and the sound fits well!
