I have tried two flavours of this stuff, vanilla and chocolate. When I tried the vanilla I thought I could taste the raspberry stuff a little, which was a little strange at first but kinda nice once I got used to it.
I thought that maybe the raspberry-ish taste would go well with the chocolate flavour a bit better and boy was I right. This stuff tastes at least as good as chocolate milk bought from the shop (I mean the good stuff like Wave) I usually blend this with a couple ice cubes and pour it into a separate bottle to take to work with me (Wave bottles have a nice lid which seals well).
One scoop mixed with about 450-500ml-ish of milk has a nice smooth texture and a real good thickness, not thick like pancake batter but thick enough to be a proper shake. It has a low sugar content, a little bit of added fiber and some other stuff to help melt the fat and also has an uncanny way of stopping hunger. It doesn't exactly fill you up, per se, but once you drink one you find that you just don't really need to eat that pie which was so tempting 5 mins ago. I'm pretty sure this is a winner.
