Example Input: I've been drinking/using the fresh Goat's milk for years. I've recently bought the dry milk<a href="http://www.amazon.com/gp/product/B001E5DZTS">Meyenberg Powdered Goat Milk, Vitamin D, 12-Ounce Cans (Pack of 3)</a> in hope of saving a little money. It does taste a little powdery. I can't drink it straight, where I used to with the fresh. I noticed on the Amazon page where it says....customers who bought this also bought....evaporated goat's milk<a href="http://www.amazon.com/gp/product/B000EY5COG">Meyenberg Evaporated Goat Milk, 12-Ounce Cans (Pack of 12)</a>. I'm wondering if this makes it creamier or taste better. I hope to get some feedback from those who have tried combining the two and what quantity of dry to what quantity of evaporated? I'm trying not to give up on the dry yet. Thank you, Vicki

Example Input: I've tried a few different flavors of Switch and this is my least favorite. (My favorite is the cherry.) Unfortunately because I didn't enjoy this flavor I didn't find it as refreshing as the others.  I quickly handed it over to my son who does like kiwi berry flavors and he did like it a lot. Of course, since it contains enough vitamin C for a whole day, I felt just fine giving it to my child, too. No preservatives, no added sugar. I like the carbonated soda product a lot, just not this flavor.  However, the biggest flaw with this product is that it's too expensive in my opinion for the little cans you get. Rounds out to about $1 per can. Less than you pay often with a vending machine but twice what you pay for a flavored water or vitamin C juice pouch when you buy them in larger quantity. Not worth it. :(
