Example Input: I really like this translation and the accompanying study guides. The quality of this specific product is excellent as well. However, I had to return it because the print was just too small for my 70 year old eyes to read easily, otherwise I would have given it 5 stars.
Example Output: 4

Example Input: I bought these bottles to use for homemade kombucha. They work great and I actually like the smaller 8 oz sizes. The tops are sometimes very hard to unscrew, which I suppose can be a good thing.
Example Output: 4

Example Input: The steamer works great. Actually much better than I thought it would. I tested it out on my most wrinkly pair of pants and I was blown away. I am having an issue with the soft touch button on the back bottom surface. Mine doesn't seem to work therefore had a really hard time turning it on and off. I actually couldn't turn it off appropriately I had to unplug it and it caused a spark. Overall performs well but still has some bugs to work out pertaining to the soft touch button.
Example Output:
