Input:
I purchased this cooker just over 6 months ago.  Don't know what I would do without it now!

The cooking speed and ease of use has converted me to pressure cooking.  Now I am cooking roasts, chickens, etc, that I never have before (because of the time required).

Plus, pressure cooking is more energy efficient--what used to take hours in the oven, now is done on just one burner in less than an hour.  You save on gas/electricity energy costs!

Glad I purchased the stainless steel cooker--clean-up is easy.
