Thanks so much for taking the time 2 write your informative findings in your blog. I was interested in getting a medical grade unit if possible, but I didn’t think they made one for this purpose, until reading your blog. I’ve been looking on the web for all the possible units sold & did not see anything of the FlexBelt or any units made specific for Abs listed as medical grade (other than TENS units which work great for their many varied purposes – just not made for this purpose). So I was thinking of buying the Contour Ab Belt, like your wife bought. I know if an EMS unit is made right & used right, EMS stimulation can work if you stick w/it & don’t expect it to result in over-all weight loss. I know EMS units work extremely well w/facial muscles & keeping the skin toned & preventing facial sagging & “turkey neck” as you get older. {My mother used a facial EMS unit 2x a week for more than 20 years & always looked 20-25 years younger than her age (w/o any facial surgeries). It works & looks WAY better than any face lift}. I know it’s only meant to tone muscles & tighten loose flab – which you can get even if you’re 40 lbs. overweight (depending on height – the taller you are; the more weight you can carry w/o looking overweight) I mean it’s possible 2 be overweight, but have a waistline, & still look like everything is smooth & all in the right places. If you need to lose weight over-all, looking for success thru spot reduction will only result in disappointment – there’s no such thing. But you can redistribute it. Although, no one should expect to see a very defined 6 pack waistline unless you have a very low percentage of total over-all body fat. Again, thank you for posting this! I will look to buy the Flexbelt & research more to see if there are any other medical grade units. I will also let you know what my results are with it. If I didn’t read this, I would have most probably bought the Contour Ab Belt like your wife did! Thanks!
