I tried a F'real Vanilla Milkshake from a QuikTrip convenience store and mixed it on the 'regular' thickness setting.

The vanilla taste of the milkshake was pretty good, and it wasn't overly sweet or overly vanilla-y. The milkshake seemed to be melting quickly, so I might try it on a thicker setting next time I have it. Overall, it basically tasted kind of like a soft serve ice cream that had been blended into a milkshake.

I wasn't able to finish my milkshake so I put it in the freezer. When I ate it later, I ate it as ice cream, and it still tasted pretty good.
