A bit too sweet
I changed to this brand due to the chemical taste of several other brands. This has no chemical taste but is a bit too sweet. If they would tone it down some I'd give it 5 stars.

It's decent
Definitely not worth it at full price but if you can score it when it's on sale it's worth it. The in store body tech one is more flavorful and mixes better by simply shaking vigorously. The macros on the ISO are only slightly better. I guess if you're in a cut it plays a difference, but if you're maintaining or bulking it really doesn't

Texture changed
I feel like this protein texture changed. I order this product every month and the last one I got feels like a little sanded on your mouth.
