Ex Input:
I ordered this for gifts around Christmas time. I actually was hoping to use it for our Christmas day meal. Two out of the four jars I ordered were rotten and inedible. I never did get to try it and I was very annoyed and disappointed!

Ex Input:
My honey has a serious sweet tooth, which I accommodate by preparing him a weekly dessert. Martha White's Muffin Mix is very convenient to prepare because it only requires one-half cup of milk, which I toss into my cuisinart; and wah-la six beautiful muffins with virtually no prep time. They are moist, delicious, and economic.

Ex Input:
I was really worried when I ordered this that the phantom power would make it overheat, apparently I was worried for nothing! I use this paired with a Blue Yeti Pro, a seriously beefy microphone, running over shielded cable that is about eighty feet away, It's absolutely great!  The one downside that I have seen from this piece of kit: It will occasionally not register as a USB device, Granted I only have seen it happen once, but you will always want to double check your connections!
