Much, much quicker than a slow cooker...and in my opinion better. Cheapest by quite a few quid and good reviews.
Here's what the manufacturer states:
Join the pressure cooker revolution! Tower pressure cookers cook foods in about a third of the time while preserving 95 per cent of the vitamins using almost 90 per cent less fuel as well as locking in all of the flavour.
