Types of Sauna Belt

I learned that there are different types of Sauna slimming belt, i say digital sauna belt and the magnetic belt, i not sure which one i will really buy but both of them are really great, they can burn belly fat for you, so you will get a slim and flat stomach, this is good because you can wear them everywhere without you sweating, you can use it in the office while you are using your computer, i think the price of the sauna is affordable. i really hope that this is effective cause im planning to buy one sauna slim belt soon.
