When the flex belt actually did enter the market, it was considered as a flimsy little toy that was only there to con people into believing that they too could get awesome looking abs and six pack without any effort at all. While this was the way it was advertised and later also shown to work up to a certain extent, it was also noticed that the device was surprisingly solid in construction even though it was manufactured in China. One flex belt review even went as far as saying that it is better in its plastic construction than many of the composite and fiber belts out in the market.
These reviews heralded the flex belt as the leading competitor in the market and a sure shot success as it gave gym goers an opportunity to double their workouts without entering the gym all that often and gave fat people a chance to change their look.
