i have the newly FDA approved REALIZE band. it is 9 cc. and what is MOST wonderful about it is the ONLINE support you get withteh REALIZE band. Home - REALIZEBand.com You record your food, exercize, measurements, pictures, goals. the site will send your doctor updates on what you are eatting and your weight loss. there is also someone available live 24/7 to talk about the band and any questions you might have. VERY unique support system that i ahve jsut LOVED using to help keep me on track,
