Product review (1 stars): Bent when shipped - shipping box too small
Filter was shipped in a cardboard box shorter than the filter.  Filter was bent to fit into the box resulting in creases in the aluminum frame around the filter.  Filter is usable but not very flat.  It will not seal as well when installed in my downdraft range.  Other than shipping problem the filter is of lightweight construction but adequate for the task.

Next time I will purchase locally.
