Example Input: Just opened the box up, and it paired easily with my Lenovo Tab4 10.1 tablet (Android 7, 2017 model). Its size works well with a 10" tablet--see attached photo. So far, so good 10 minutes after setting it up. Will update review as I get more experience with it.
Example Output: 5

Example Input: My pregnant partner didn't like the smell or taste of the tea. Fair enough. But Amazon will Not allow me to return this product. Had no idea. Can't fault the manufacture, but beware this Amazon return policy.
Example Output: 1

Example Input: I bought this purse late March and in late July I could no longer close the main closure. The last purse I had was from Wal Mart and lasted me 5 years so I know that I am not hard on a purse. I bought this one because it is leather and I knew it should last longer. Boy was I wrong!!!! Don't get me wrong I love the purse. But this one must have been faulty which is why I give it a 3 star rating. I just wished it was better made!!!
