We were incredibly excited about this oven, with the intention of using it as our primary microwave, and a speed-oven.  Unfortunately, the 120v version is underpowered, making it pre-heat more slowly than our full sized oven, and limiting the advantages of the cool technology.  Also, there's definitely a learning curve to using this, including when to switch the glass plate for the metal plate, and understanding the "precision" cook technology.

I think I would be likely to highly rate the 220v version, but can only offer lukewarm praise on this one.

It's gorgeous, and we get lots of feedback on how pretty it is.
