Example Input: Stonewall Kitchen Farmhouse Pancake and Waffle Mix is definitely a mouthful in name but, in taste, not so much. Don't get me wrong, it's not bad but, you could find any number of "mixes" that taste just as well and some even better. I know my taste buds aren't the same as yours so, what's just decent to me may be great to you. I also wish I had bought just one can instead of 2 huge 33 ounce cans. I finished the first can, I'll give the other can away and, I'll continue trying other mixes until I find the "best mix" out there. So far I seem to only be satisfied with a homemade mix for my waffles. My preference is for waffles over pancakes but, this didn't make it on either count. I even tried adding things to it but it didn't really help. Maybe it's just me. Try it if you like but remember, buy only one can just in case you're like me. You can always buy more.
Example Output: 3

Example Input: there is a taste of sugar substitute, the aftertaste turns me off, I've even tried using a little bit of milk in the mug before hand to hide the taste. It didn't, so i'm just using Swiss miss powder and a little milk to make it a creamier hot chocolate before using using my keurig.

Example Input: I bought these for the office and no one can put them down. I'm ordering more today and it has only been 2 weeks. Didn't have to shop for them either, Amazon brought it to my door!
