I have used lots of different protein products (among other things) and this one seems to work well. I previously used Muscle Milk Protein Plus, but after Costco stopped carrying it I couldn't find it any more. Since my wife uses it too I had to get something with ok taste, low calories and high quality protein and this one does the trick. I am not a big fan of the sweetener (natural, stevia I believe) so I ended up blending in a scoop of the Muscle Milk pure whey for flavor. My wife doesn't mind the stevia so she is good with this product by itself.
