I tried these a while back with a coupon I had. I remember liking them, however I recall them having a bit of a metallic flavour and I don't believe the filling power lasted long enough. The protein isn't as high as a whey protein powder shake so you don't stay full for as long as would be ideal. For something quick on the go, they're great but I think I'd rather mix my own protein shake in a to-go cup.
