Product review (4 stars): Does the Job!
Very good booster fan. Would not initially work as I believe there was a temporary bearing issue. Called owner of Acme Miami( as others have indicated in reviews) and I also found him to be very helpful. I agree with all of the comments about the legs, they are not very secure and the sheet metal screws need to be tightened. When first installed, check the fan periodically to make sure the pressure sensitive adjustment is adjusted so that the fan is cycling on when the dryer is first started, and shutting off when the dryer cycle has ended. I had to adjust the setting twice. Would agree with other reviewers who also feel that the inflow and outflow openings should be reversed to reduce the number of elbows. That being said, I'm pleased with this booster fan and the plug-in ease of operation.
