Ex Input:
This book did not have much helpful info. It was basically about getting a horse to do anything. She had way too many tips on how to train your horse. There are ways in which all three children can learn. I found myself skipping over those parts because the information was nothing new. Not worth buying.

Ex Output:
Bad review

Ex Input:
The power plug fell out within 30 days of purchase with light use. It won't stay in. Had to buy replacement.

Ex Output:
Bad review

Ex Input:
Failed on 5th month to date. Worked great at first, but then started having major issues over time. Not worth it. Going back to Western Digital. At least they will give you 2-3 years of service. But if you're building a data system or doing any amount of file transfers -- look elsewhere.
