Easiest one star review ever. I'm writing this with bloody fingers from assembling this. Multiple poles were bent, none of the pole connectors worked, the hex wrench broke in my hand, the screws didn't really go into the holes provided (I had to get a friend with a press drill to widen the holes to make it work), there are sharp edges on the poles where there is a seam, and doesn't look that great once assembled. Easy do not buy, the only reason I didn't return is because it would have been tough to disassemble the half I got through in the first 5 hours of building (mostly spent fixing the product delivered)

Excellent prevention/cure for hangovers

Flavor Name: Original Variety

Love there. Taste is great. Bought these because my local grocery store was out of stock and didn’t want to pay $4 each at the gas station. Excellent prevention/cure for hangovers or general dehydration if in the heat excessively.

Life changing

Flavor Name: Original Variety

I've tried everything for severe cramps and dehydration. Years of suffering with no sleep due to severe cramps. This is by far the best..its better than liquid IV or any hydration drink on the market, even better than pediolite. The key ingredient that helps me most is the magnesium! This product changed my life!

Must have for rehydration

Flavor Name: Original Variety

I spend all summer working on AC units. Sweating every drop of moisture out of my body. This is the ONE and ONLY product that will put back the nutrients, vitamins, and hydration back in your body at a rapid rate for me
