Got this cheap at Winners, heard of people using it (no actual comments about it), so decided to give it a go. I've used protein as a meal replacement/appetite suppressant before.

Flavour was incredibly disappointing -- bland and weak, like watery hot chocolate. Clumps remained no matter how much I used my shaker.

Not terrible, worked fine, but I wouldn't buy it again (but perhaps the vanilla is better, I don't know) -- I'd recommend GNC's own brand instead, better flavour and dissolves with no issue.
