Strawberry Coldest Hydration Electrolytes Powder

I was really hoping that I would like this because it said it had no artificial sugar in it. It does have Stevia in it which is a natural sugar substitute, and anhydrous glucose. The instructions say to mix one package with 21 ounces of water. I have no idea why they chose 21 ounces of water to mix the package with. None of my water cups, bottle, or mixing containers held 21 ounces. An average size measuring cup holds 16 ounces. A large water bottle holds 32 ounces. I wanted to do a proper review so I ended up having to measure out exactly 21 ounces and find something big enough to hold that amount of water and some ice and then mix it. It's not quite big enough to make a full pitcher, but too big to make just one glass for an individual. The taste is very very sweet and somewhat fruity. Not really strawberry but almost. The first few sips were fine but sweet. But after that it left a very bad after taste in my mouth. I realized it was the stevia that I was tasting. Some people don't mind it but I am just not fond of that taste. I felt like I needed a glass of water to wash it down. I would have much rather they used real sugar and added a few more calories. This would have been a fine product if they made the mixing instructions a normal size container, and not used Stevia.
