I absolutely love the Presto version of this pressure canner. I've had it for a while now. At first I did not like that I can only do 5 quarts at a time, but now I actually prefer it.
I make a batch, run it and just open the lid after it is all done. I let everything just sit for 24 hours and pull the jars out later.
Before when I would do my canning, I would effectively take up the entire cabinet. Now I just take up about the space of the canner with just a little area around it.
Ball makes a version that is strictly for water bath canning.
Mine can also be used for water bath canning. It has instructions for both.
