Am familiar with ISM band 27 MHz industrial sealers and impressed with the new induction cookers which use the same technology. They are more efficient and faster than gas or microwave,and more versatile. virtually impossible to cause a grease fire which is the prime reason for home fires and death.
I bought one at Wall Mart, got free delivery in 6 days, cost $58. Showed it to a customer and he was extremely impressed.
I am now trying to find a wholesale source for these but I no longer have a store.
