Hi – I’ve been using the Flex-belt everyday for a year now. It really does work!!! I haven’t tried the Contour since my flexbelt works well – and their customer service is awesome. You do have to buy more gel-pads – and they last about 30 days (but I’m also using the belt 2 sessions a day). I like that the belt uses batteries because I use rechargable and so I don’t have to worry about running out of juice for my workout session since I always have the batteries on hand. The flexbelt belt does say you can use it for other areas – not just for your abs – it has an upper and lower body mode. The key point for getting ripped abs is not just exercising but you also have to have a HEALTHY diet – which includes good carbs – like whole grains…and not eating a lot of the carbs… sorry – but its the truth! (and I love my carbs) I also have an active life-style – which means I work out EVERY DAY – most days it the treadmill – 3 miles minimum. I use the Contour as part of my daily workout routine. I love it because I can multi-task and work out. If do you these things – you WILL get results and have a ’swim-suit’ ready body. Best of luck and I hope this post helps you out!!!
