Q: Why didnt I read the reviews! Typically like vital proteins but this stuff is awful. Taste terrible and smells like vomit. I'm trying to drink it anyway because it was expensive but yuck.

A: negative

Q: Used it in birdbath to keep water from being stagnant- put it in my dog’s swimming pool - it’s fun to watch and turns off when water dries out. I recommend this!

A: positive

Q: Purchased this for a short trip to Asia and it worked really well. I used it for charging my Ipad, laptop and phone. But the most impressed part is now I can use my travel hair dryer and curling iron hair straightener with this thing so I don't have to search for the local hair salon before attend the exhibition or dinner!!! Highly recommend!!

A:
positive
