30" Stainless Steel Under-Cabinet Range Hood — 900 CFM | ROBAM U2

Like it so far. top round duct would be the most straight forward installation cuz 1. the manual does not explain how/where to cut the plastic pieces for rectangular duct either way, plus it seems to be relatively thick and hard plastic idk if a regular scissor or wire cutter would do the trick 2. the rectangular duct adaptor has to be sourced separately and it was nowhere to be found when we purchased our unit. a representative told us they did not have enough stock to meet the demand at launch but more would come by the end of July so hopefully it is now resolved. we ended up doing extra duct work in order to get the top round adaptor came with it fitted.
