Product review (4 stars): The motor was floating loose inside the blower assembly. ...
The motor was floating loose inside the blower assembly.  I had to disassemble and install the motor isolation mounts as they were not attached to the motor and installed.  I found the motor isolation mounts rolling around loose inside the box that the blower came in.  A complete assembly should be able to be installed out of the box not have to be disassembled and reassembled to make a working unit.
