Product review (2 stars): No support, nice product, if it didn't break.
I purchased this hood for my parents remodel about 8 months ago.  It is a nice hood however, there doesn't appear to be any technical support for it.  The control button housing cracked and crumbled (it is a very brittle plastic) allowing the buttons to push through.  It is a modular piece which would be easy to replace if I could find a source for it.  So far, there has been 0 technical support.
I'll update this report if it changes.
