This is our favorite of many items we've bought from Anker. We love having the wall charger, retractable cable, light weight, and small size.

Ex Output:
Good Review

Ex Input:
Interesting book. A bit too much for me, though. The authors spend an excessive amount of time talking about their philosophical views.

Ex Output:
Good Review

I chose this book because it wasn't a bad read, but not her best either. It was okay and entertaining. I'm glad that she wrote it. So many books are so terrible. But it's good. Like I said just don't expect greatness. A lot of the people who left positive reviews must be family members or friends. It's easy to read if you have nothing else better to do. Don't believe me? See what their other revues are.

Ex Output:
Good Review
