Example Input: I purchased this mostly for books (daily use) but I also use it for HBO GO & Netflix when I don't have my iPad on me. I have a ton of problems with HBO GO loading. Sometimes it'll go days with out it working. Netflix doesn't seem to have these problems. Also, I have found on numerous occasions that it will not power on when I want to use it. I have to hold the power button down for 30 seconds & restart. Since it's not my go-to tablet it's okay but I think i'd be much more disappointed if it were the only one I owned.
Example Output:
just okay
