I was looking for a tablet easy to take along mainly for the mobile Internet and significantly larger display than a smartphone. Sim card was immediately recognized, lasted less than 2 minutes from the tuck to start surfing hats (tablet was of course previously established), 3G network is now almost everywhere. Contrary to the opinion of other buyers: SIM and memory card go well easy in and easy out well again. The Android version is ok for me, of me used apps run smoothly and smooth to play, I can not say anything. The screen is nice and bright, has good contrast and is for me outside facing away from the sun easily recognizable. It responds promptly, need only occasionally an extra invitation. The dark blue case is indeed plastic, looks like haptic very valuable. The sound is rather mono, but crystal clear, even with earphones without glitches. The battery seems promising, was not empty even after a day of continuous fire. For long-term behavior, perhaps later. Have previously had good experience with Lenovo devices and was not disappointed with this part.
