Example Input: I'm a seed addict. My favorite brand was always David s Low Sodium, but they are hard to find. I tried these and they are my new go-to. They don't claim to be 'low-sodium' but they definitely have lower sodium than regular seeds. I think they even have less than the low sodium in the other brands.
Example Output: 5

Example Input: I bought 2 of these as gifts and heard great things about them so I bought myself one. I am so pleased with this. It keeps my coffee just as hot as when I pour it in my cup which is how I like it! But if you dont want it that hot you just turn it down. I like that it has a digital read out and easy off on digital touch.
Example Output: 5

Example Input: The material on the exterior feels cheap and not what I expected. I order the extra large striped bags and got these instead. Returning as soon as possible.
