I have ordered from them for years. I can only speak to the Wonder Slim Protein shakes and bars, but I can honestly say they taste wonderful! My most successful attempts at weight loss in the past have been using these products as part of a modified fast (drink shakes for Breakfast & lunch, one lean/green meal at night). I have literally survived on these shakes and bars for months on end (several times), which I could never have done if they tasted nasty. I actually just got a new order in the other day to get ready for my full liquid stage post-op (being banded on Wednesday).
My favorite flavors in the shakes are chocolate & mocha, but I also like the chocolate mint pretty well. The vanilla and the strawberry are great too, I just don't reach for those flavors as often because they're not my favorites. The Protein Bars are excellent too, my favorites right now are the oatmeal cinnamon raisin, chocolate chip cookie dough, double chocolate, and chocolate mint. They really do taste like candy bars! I have actually used them as a "treat" before instead of a candy bar and they are quite satisfying to the sweet tooth. I'm not going to list all the nutritional facts here, because you can see them on their website, but they are high protein, low fat, low calorie, good choices.
And no, I'm not affiliated with them at all, just a happy customer!
HTH!
