Puressence Unsweetened Flavor Water Variety Pack, Makes 36 Drinks, No Sugar, Zero Calorie Drink Mix, (2 Cucumber, 2 Peach, 2 Lemon)

Los sabores están horribles, casi que prefiero tomarme el agua sola. Habia probado los que venian con mi botella que son "lifesip" y esos si tenian sabor agradable.

I only used one of them and the flavor was good. But unfortunately, I couldn’t use it. Because I had to send my cup back. Which was sad cause it was a great idea. Just their cirkul cups are horrible. At least the one I bought.

This one is the best. No artifical sweeteners at all.

You ever wonder what it would be like to drink a fruit that's been sitting in formaldehyde? Wonder no further, if you buy this particular Cirkul product, you're definitely going to find out what that tastes like. As soon as I took a sip I wanted to throw my Cirkul water bottle and my wallet at oncoming traffic. What a total waste of money. Anyone saying that it's subjective has never tried this particular flavor pack. I seriously tried to give this a chance and even checked out the other 2 flavors included but they were same exact result. I feel like I've just found a way to embalm myself drinking this terrible excuse for a flavor pack.

Puressence have no natural or artificial sweeteners. They are a hit, and seem to last a good while (close to a week each, drinking one bottle per day).
