I checked my local stores and didn't like what they had. My mom have always used a Presto pressure cooker, so she recommended it for me. I had an aluminum pressure cooker that wasn't suitable for my new glass top oven, so its base wasn't completely flat and was taking 15 minutes to start whistling. I tried Presto pressure cooker yesterday, and it started whistling just after 3 minutes because the base was completely flat which worked perfectly with my new glass top oven. The whistling sound is very minimal, and the quality is really nice. It's also light weight, so it's easy to clean. I'm so happy with my purchase.
