Herbalife Shakes

Anyone using this stuff.  I'm going to a presentation on it tonight and just want to know if it's been effective for anyone on this board.  I'm struggling with the shakes I've been using (nasty), so I'm interested in trying something new.  If this is a good alternative, I'd love to hear about your experiences with it.

I love them but the carbs are high. I use their personalized protein powder that you can add to anything to get additional protein. It's 20 calories, 5 grams of protein. No carbs.

I'm pre op and I use it everyday I like the French vanilla.
