Solid product that a duct won't fit on.
6" round duct more like 5x7. Hole was hacked out that way. Quality control isn't much of a concern. Bad day in Guangdong.

Fits Well, but Entry Size Misleading
Fits in the small space available, but connecting the supply duct was a problem. This listing says 6" entry, but 6" supply duct (flex) will not fit (too small). Going to spend more money to purchase an adaptor (6" to 8") to see if that works. This whole thing has cost >$170. so far (incl. diffuser).
