Thinx: the new Aunt Flo undies?

Sandy
Have anyone ever try the leak resistent panties from Thinx? (To those who dont know, you can substitute the pads and tampons to the panties. I got UTI from wearing pads because my lady can't breath down there covering up, and I don't like tampon. So my next best thing is the panties they're advertising. Is it true that it work, or no? Please tell me what y'all think, and y'all experience with it. Thank you!
