Ex Input:
I bought a new bread machine and bought this collection of bread mixes as well as some single mixes to try it out.  The single mixes worked well as they included yeast packaged separately in the mix.  My machine states clearly not to get the yeast wet, to put it on top of the flour away from the water.  The mixes in this collection have the yeast in the flour, not packaged separately.  The bread failed to rise at all.  Why would they package the yeast separately in the single mixes and not in the multi packs?  Along with the Heartland Collection I also purchased the Baker's Choice Collection.  I am throwing them all out.  Don't waste your money.

Raving reviews made me buy this for dogs. I have a lab mix a beagle and 2 Shepards that I got from impoundment and they're not spoiled. One chewed it to crumbles but left it on the ground and my Shepards have been burying them in the backyard. I wasted my money on this one.

If you are really thirsty this drink will be a welcomed choice, although almost anything would at that point.  However, I did not like this flavor as much as the Switch watermelon strawberry flavor which I found extremely refreshing.  The Kiwi Berry is also 100% juice. Although the drink is good, it has a strong syrupy berry flavor which reminded me a little bit of the Robitussin cough syrup I dislike. I also didn't taste any kiwi.  At 135 calories for an 8.3 fluid ounce can you might want to drink it sparingly.
