Input:
This pressure cooker is amazing! I have canned about 10 batches in it so far and I haven't had any issues. It works perfectly! I am so pleased with this product. I used to have a presto pressure cooker that I used for general cooking, but that thing made me so nervous! It seemed so flimsy and poorly made. I would generally hang out outside (within earshot to monitor the rattle) because I really thought that thing might explode. I NEVER would have attempted canning with it!
