I have one of these things and it works really well on a gas stove. I haven't tried it on an electric stove. It doesn't have a totally flat bottom which makes me wonder if it would work on one. There are two big pluses to this thing: 1) You don't have to wait for a large amount of water to boil and 2) You don't have to dea; w a heavy pot full of water. I think these have been used forever in other countries and have FINALLY been approved for use here in the States. 7 quart jars fit on it at a time. I don't plan to ever use a big pot again for water bath items. You just use the processing times that you would use for regular water bath processing.

I do a fair amount of canning and it seems the most tedious part is bring water up to a boil. This cut the time way down and save energy in the process.
