Tastes just like a fudge smoothie and works great! BUT..... that price change is BS. Finding another product until it changes back to something remotely reasonable. Sorry not sorry.

Great product that works well but it’s not worth 100 bucks! No way. I mostly used this to add to my daily carb/protein count and as a post gym shake but I’ll have to find another source now

Love the product but the price increase is ridiculous. Will not purchase again until it drops to a reasonable price. Shame on the greediness.

Awesome product but the price? Why a $30 price jump? Well, I just purchased this from amazon and they still have the old price...

Loved this product, was a regular user but jesus that price increase to $99 is absurd! Not touching it again until that changes, if it ever does. I'll have to find something almost as good.

One of the best protein poweder that I've tried. It mixes really well and it has a very good taste. For muscle gain is the perfect combination since it has 60g of protein and just 650 calories.

Love this product and have used it for a very long time, but after the price jump to $99, it just simply isn't worth it for me anymore. Way too expensive. Very disappointed in ON's decision to raise the price on this, and will not be purchasing again until they drop the prices significantly.
