Overall a good product, simple and easy to use ... BUT ..

... But significant adverse areas for improvement:
1. The plastic of the cooking bowl, though apparently good, starting to crack after 4 to 6 months.
After 1 year of regular use, it has become unusable: The big plastic pieces have disintegrated (in preparations ???).
It is of course not covered by the warranty and I seem to find one as a spare part ...
Conclusion: Life span: 1-2 years maximum !!!
2. When you return the bowl of burning water escapes through the hole (!!! DANGER BURNS !!!). It would be enough of a drip system.
3. A lot of water collects in the bowl (and therefore in the preparation) cooking requiring the opening of the bowl to remove it: A new risk of burn with the vapors and the elements that are boiling.
