Product review (4 stars): Very Pretty and would buy again, though a multitude of issues.
It's really a mixed bag.  The customer service was great, the look of the object was great after installed, but there were issues. Would I buy it again?  Yes. For the work involved do I wish it was closer in price to their non-glass model?  Yes.  Do you have to know your way around tools to be successful? Yes.

1. The glass left to right was not level.  You may have to move the control panel metal UP, rather than tighten the glass (these screws are left and right under the filter covers).  In the end I had to unscrew the glass on the right to match the gap on the left.
2. To confirm the Fan is hooked to the wall bracket, after removing the filters look inside behind the motor fan.
3. The transformer board was cracked (both LED did not work), so check all functions BEFORE install.  Again customer service from the mfg was great in shipping me a new one.
4. The lower metal shield holes did not align (see picture).  You have to drill new holes and secure with self drill sheet metal screws.  Note also in the picture the fan vent white plastic is cracked from tightening the screw too much.  Not likely from shipping forces like the control board.
5. My fault, I didn't realize the metal cover started AT THE GLASS instead of at the top of the motor housing, making my measurement off.  This caused lots of sliding up and down of the higher housing while I fiddled with the upper bracket on the wall. Sliding up and down caused scratches on the metal.  Don't slide it up and down if you can.
6.  Finally  finally, rub the whole thing down with vegetable oil or olive oil to get rid of the finger oils.
