This is an awesome idea! It comes in VERY handy when out and about to charge my phone. I love that I don't have to put a cord in my purse and worry about it getting tangled up anymore. I love that I can wear it as a bracelet, it looks awesome! Genius idea! I am very very happy with this purchase... You won't be disappointed!

If you just need to consume some calories and protein, this works. It definitely doesn't taste amazing or even remotely natural, and it's a bit on the thick side, but for convenience it's completely fine and the after taste dissipates pretty quickly. Tastes a bit like cheap chocolate with sweetener but as I said, the taste fades fast.

Be warned - if you need to use this for a cup or bottle with a handle, it won't fit. For a water bottle, it's great. For a travel cup with handle, look elsewhere.
