When I first received this belt, I thought it surely wouldn't last.  That was two years ago.  Honestly, I'm amazed at how well it has lasted, since I wear it at least four days a week.  I got the black version.  You have to follow the instructions on how to adjust the sliders, btw.  If you do this, they work perfectly.  Anyway, it does what it says.  It's invisible, it gets rid of the gap problem I constantly have with pants.  I already have a tummy, and it doesn't add it it because it's ultra-slim.  I often wear tunic style shirts over my pants, and with this belt, there is no visible "belt-bump" whatsoever. You would never know I had a belt on.
