Example Input: I like the fact that the music is battery powered! No winding like the old days! Also, you can put music on an SD card and play it in addition to what comes preloaded. Looking forward to using it!
Example Output: 5

Example Input: I ordered from Amazon because the only 5oz cups locally seem to be child oriented and not for an adult bathroom. Ha! My dixie cups have riddles on them and are as cartoonish as the ones I could have bought down the street. I'm throwing them out and getting a hard plastic cup. So mean to send something other than was pictured!!!
Example Output: 1

Example Input: Magnets are weak, there's only a few small ones on it. I use it to put plastic name tags in so it doesn't weigh very much at all and it could not hold them up. I just attached a Velcro strip to the back of mine so it's not a huge deal but if you're not wanting to do that or glue more magnets on the back you will not be happy with the product. I also noticed one side of it on mine is not attached.
Example Output:
