Example Input: I love these! The price is VERY good...all the flavors are really good! The peppermint one is my favorite and I would gladly take more of that before the others. Though the others aren't lacking at all, I'm just a peppermint fan! Will be buying more when my others get low! Thanks so much!
Example Output: 5

Example Input: You know I really do love this product. I wish I could give the tea 5 stars because it really does brew up a very pleasant tasting iced tea that needs little sugar or other embellishments. The problem is it's loose and when you  are trying to make a big jug of it with two packets of tea it is a huge mess to strain. And ordinary double mesh strainer is not fine enough. I don't have coffee strainers in the house so I had to line a mess strainer with paper towels and it took forever to strain. But when I strained it with just my mesh strainer there was a ton of tea in the jug. I wish the variety pack came pre-bagged like the smaller boxes of tea do.
Example Output: 3

Example Input: After years of using synthetic sweeteners like Equal and Sweet N Low, I realized their long-term effects and wanted to find a good alternative. NuStevia was a lucky discovery. It has virtually no bitter aftertase, it's all natural and I've been using it exclusively for more than a year now. It works in both hot and cold beverages and comes in bulk and in packets for portability.I haven't used it for baking and probably won't because the chemistry of most recipes depends on sugar or something similar to get a good effect. However, for daily use in beverages, this product is very good.
