Finally!!! I've tried other caffeinated waters off of Amazon before, but this one takes the cake! For some reason, with those other waters, I get a metallic aftertaste that is strange and artificial. Perk²0 tastes natural, clean, and has no hint of anything other than pure water.

Don't get me wrong, I love coffee. I just hate the fact that it stains my teeth. Perk²0 is awesome if you want a bit of kick without having to worry about yellowing or coffee breath.

I have a bad habit of enjoying liquid calories. I picked up Perk²0 when I started my spring diet last year, and I've been a loyal customer ever since. If you're looking for a health conscious way to get through the day, look no further. I've also had great customer support experiences with their team! Highly recommend!!
