have y'all seen these products?

they completely weird me out, but to the point where i had to try one ... just for the heck of it!

i tried a calorie free pancake syrup
i did a review you can see here: Review

i am just wondering if anyone else has tried any of these products, or if they just sound too sketchy. And also if y'all even believe their claims ...

i see the appeal in these products (for weight loss / diabetics) but i generally feel apprehensive due to the nature of the products, i assume they are very artificial and perhaps not so great for health over the long haul. I think i would rather just splurge on the real thing every once in a while.

what do you all think ?
