Confetti cake flavor is like super super DIVINE
I definitely love the confetti cake flavor, got some colored sprinkles inside and literally sooooo good, best tasting ever. The formula is also super good for a protein shake at any time:)

10/10 would recommend
I typically buy chocolate protein because its always the safest but I decided to branch out after reading these reviews. I bought the fruity crisps and wow. Amazing taste. Its ok with water but its a complete game changer with almond milk! definitely five it a try.
April 17, 2019
I bought the vanilla and also the cinnamon toast flavors. The vanilla is tastes fine, but in my opinion, the cinnamon toast flavor is way too sweet. I have mixed it with water and also tried mixing it with coffee to lessen the sweet....but still way too sweet for me; and while the flavor is good, I really wish it weren't so sweet. I will be taking it back for a different flavor.
The product itself fills me up and keeps me satisfied for a good few hours after taking it. I usually buy the JYM protein, but tried this for something different.

Fruity Crisps - A Protein Snack
Drinking a protein shake is no longer a chore. The delicious flavor of Fruity Crisps tastes just like the leftover milk at the end of a bowl of fruity cereal. It's not overwhelmingly sweet and has the right slightly-thick consistency while mixing easily with water in your blender bottle. I truly look forward to drinking this protein and best of all, it's easy on the stomach. Highly recommend!
