This Ultimate Nutrition whey-based protein powder is the best I've found for making a quick protein shake (with plain water) as a meal substitute or protein supplement. 
Overall, this is a great product that I can confidently recommend.

I can digest this without issues, no bloating. I don't digest well Whey and Casein proteins and I need to avoid cholesterol and high fat. I did tried the Iso Sensation one which is great but I find Carnebolic to digest better in my unique case.

This is a protein that works hard on your muscles and goes easy on your pocket... I have used three flavors so far: "Strawberry", "Raspberry" & "Chocolate Cream" - "Strawberry" tastes the best (try it with Apple Juice - it tastes tooooo good) and the not so great taste has been "Chocolate Cream". Coming to the nutritional facts: If you compare it with all the other available brands (ON, Dymatize etc) it has the best amount of protein per scoop (25gms per 30gms of scoop).

It is just what I was looking for. I use this to make a very low carb bread that tastes great and I also use it to make ice cream. I like the unflavored or natural for these items as I can always change up flavors to what I want. It works great for me and would highly recommend especially using the way I do.

You can't beat the price and taste or this protein. I've bought the Vanilla Creme and Chocolate Birthday Cake and have no complaints! I will indeed keep buying!!!

This is my first use of Ultimate Nutrition ProStar Whey Protein. I love the violet-blue container it comes in - very stylish. The protein goes in very well with warmer water. Cold water takes a little longer. The second best thing about this protein is the low fat, sugar, and calorie content. The best thing is the excellent strawberry flavor. I highly recommend it.
