Product review (3 stars): Some hesitation
I expected that this was made by Eureka (as in vacuums), but it is not, and there is no way to contact the manufacturer or know who it is.
Then, this hood is 29 1/4" wide--why not a full 30"?  I had to make and install filler strips.
Next,, there might not be a mounting template, and the instruction booklet is cheaply printed so that it is hard to read the diagrams.  The instructions do not say so, but the interior shell has to be removed to tighten the mounting screws--only four machine screws hold this shell, and the threaded holes in the outer shell are flimsy and tend to strip when you tighten the screws.
Next, the damper does not seal; it's smaller than the duct.
Finally, the venturi  is not completely sealed, so that some of the air drawn from the kitchen is blown back through the push-button holes; if the filter does not pick up all the grease, it will accumulate around the switch.
It does seem to draw well, however, and I like the clean design and the low profile.
