As far as I know, Reign has the most caffeine of the energy drinks. Lower carbohydrates and decent taste. I have a really low heartbeat and these drinks allow me to function.

Reign tastes great and doesn't leave an after taste. It's so good that most of the time I drink it at room temperature It provides me with a little kick to keep me going. I have narcolepsy, so when I'm driving I keep a can close by. It has allowed me to travel without the fear of falling asleep.

Love it! Reign has a variety of refreshing flavors that give you a great energy boost. It’s perfect for the afternoon pick me up or to give you the energy you desire to get a great workout in. It comes in a 12 pack and it is also zero sugar. Overall, it’s a very inexpensive tasty treat for adults. It’s smooth with no bad after taste. Definitely recommend!

We love reign, the flavors are wonderful. But, the last few cases that we have purchases have each had a couple cans that don’t have any carbonation, the cans are really flexible to push in and out before we even open it. I’m disappointed that this keeps happening because they are pricey.

This drink has a ton of caffeine to help get you going... however it lacks the BCAAs and other things that make the caffeine work better, and help your brain function better. I also dislike that it is very LIGHTLY carbonated and goes flat very quickly. Buy bang if you're going to buy these types of drinks.

Love the product, except recently 1/4 to 1/3 of the case is Flat when purchased. Not sure if it’s a packaging flaw that is overlooked or if the product is getting close to expiring. I’ve had 4 cases this way recently.

The value is great for 24 Reign drinks, but as with all variety packs, you take the good with the bad, which means taking two flavors that are ok to bad, for the one that is exceptional.

I don’t like this newer collection of flavors,the pink sherbet flavor is entirely too sweet and has a strange aftertaste! Can’t wait til that one is replaced with a different flavor in the next iteration of this 24 pack . I think it should be pretty soon.

1/3 of the cans were damaged and had zero carbonation. Live too far to drive back a to return. Not sure if it’s Reign, Sams Club or transportations fault. Just frustrating to lose so many.
