This product works! It's a great faja - but not so much for people with larger thighs!
Being that I have larger thighs than normal I always have trouble finding fajas that don't squeeze my thighs and give me those awkward bulges on my thighs that you can see through clothing.
I thought I wouldn't have this issue with this faja after reading the reviews.... but unfortunately I was wrong.

I do have to say that the faja does give you a great shape! Sizing is perfect (I'm 5'4"/160ish/27inch waist, medium fit me perfect around the waist)
But if you carry more of your weight in your legs and don't want that awkward thigh bulge then these kind of fajas are not for you.
