I've set up 8 of these for a club a while back and they haven't given us any problems. The screens are maybe not quite as vibrant as the earlier Lenovo model, but no one at the club has commented so maybe I'm imagining it.
I recorded what I did as I set them up, as before, and can upload my notes if anyone is interested (I'll just need to remove references to our club name/website etc. first). One nice thing is that you can connect two of these tablets via Bluetooth and transfer the BridgePal and Caffeine apk files from the first you set up onto each subsequent one, which is much quicker than using the internet each time.
