This stuff really works great for me! It doesn't make me shaky like some other drinks that I have tried and I don't crash after it wears off. 5 stars

The product was a no show. I never got it. After 3 weeks, I contacted the seller and told him that I had not received the product. He said he would correct the problem. I never received the product and the charges have not showed up on my account. 1 star

For the longest time my husband drank Red Bull to give him that buzz. But it's always short lived so he always brought a few to work. This one seems to be working for him. Obviously it's much smaller than a Red Bull but it gives you more boost. Not 5 hours as advertised but at least a bit longer than Red bull. He likes the taste too. 5 stars

Oftentimes when I drive a long distance I get a bit drowsy due to boredom. That is obviously not a good situation.

One of my friends told me about '5 Hour Energy' and how helpful it had been to him. I thought it was worth a try. Since then, I have used it on about six road trips and it has been great. I have not had heavy eyes on any of those journeys.

I haven't seen the research on it - double blind studies, etc., so I suppose that the way it has worked for me has been a placebo effect, but I don't think so. I plan to continue having a bottle prior to starting any lengthy trip. 5 stars

I still can't believe these things actually work as advertised, but for the most part they really do. You get a quick, smooth energy boost without being jittery, and no crash later. It's far more pleasant than coffee or Red Bull. However on a couple occasions I have felt a little weird while on this stuff, not jittery, but just a little funny. To counteract that, and also to make this expensive product last longer, I've drank only half a bottle at a time, which really seems to be spot on perfect for me. Great product! 5 stars
