Example Input: I used these lollipops for a candy princess costume for my daughter. They came in perfect condition and exactly like the picture shows. They do come in a group of 16...such a great value! I was extremely satisfied!
Example Output: 5

Example Input: I was amazed at how good this is for canned fruit (which I normally won't touch).  In particular I adore papayas and mangos.  The fruit juice instead of syrup is also very nice.  The easy pull-top on the can makes this a great item to stash in my desk drawer at work, so that I can have a fruit snack easily even if I was too busy or forgot to bring lunch.  So far I haven't gotten a can that had any problems.  The watermelon isn't crunchy - of course not! - but it's good, and certainly not "slimy".
Example Output: 5

Example Input: I was at a 5 star hotel and was served this tea during a meeting.  It was fantastic.  I asked the server if they could get me the name of the company, but they were unable.  Thank goodness for Amazon I was able to find it.  It's the best I have had in many years.  It arrived on time and very securely packed.
