Product review (3 stars): don't worry about the weight holding it up to install. Light as a feather
every time I put up something like this, I am amazed at the ingenuity that goes into continuously cheapening the product. Soon the sheet metal will be so thin that I will put my finger through it. Installed fine and works fine. Has the advantage of multiple ducting or duct free installations. No problem if you've put one in before, but some beginners will have problems with the instructions. I can not stand the plastic latch on the filter, which will get brittle and break in time because of the heat. Quality is about par for the course these days
