Personally, I have no issues with it.. especially for $50... The screen, you get what you pay for obviously..
Touchwiz, installed Nova right away anyways..
Goes about 3 days without a charge, sitting on WiFi the whole time.. I'll play some plants vs zombies 2, facebook, email... Basically, I use my tablet after work at night for everything but calls and texting.. so for me, battery is excellent.. ymmv..
Hardware wise, I don't play an over the top games or anything like that, so it keeps up always with whatever I'm doing..
I'm happy with it
