Good protein option with good taste
Flavor Name: Chocolate, Size: 11.5 Fl Oz (Pack of 12)
These shakes are delicious. There are a few things about them I love. First, they are gluten-free. Next, they are low in sugar. They are also low in calories, and are very tasty. They do not leave an aftertaste like a lot of protein shakes. I do find you need to really shake them well to get a good consistency. They are not clumpy, but sometimes have strands that give them a weird texture. However, this does not happen if you shake them really well. I like to blend mine with fruit, and never have this problem when I do that. They are also really convenient because you can grab them and go. The serving size is perfect too. I would recommend these if you are looking for a low sugar, protein drink.

Incredible, perfect
Flavor Name: Zero Ultra, Size: 16 Fl oz (Pack of 15)
This is definitely the best flavor of Monster! No calories, but full flavor. I can't get enough of this stuff. It does cost a bit, but it is worth getting every once in awhile as a treat. I love it, and I would definitely recommend it. There is a high level of carbonation, so it doesn't go flat too quickly.
