Product review (4 stars): Decent product if you're patient and handy
Order took three business days to ship.  USPS delivered in 36 hours from Lancaster PA to Minnetrista MN...very good.  Package from USPS (Priority Mail) was undamaged, but internal contents (in box) were not packed for shipment (zero packing) so motor/bracket was bent 90 degrees and penetrating box while all other parts had been ripped from their bags...hope all aren't shipped this way. Being a universal fit made straightening/repair OK, but in addition, motor ran in wrong direction, so had to be disassembled. Never seen one run this direction, but knew I owned it at this point and original was screaming, so I reversed the armature.  Supplier was  "snarky" when talked to about delivery.  Several of us have noticed that Amazon seems to not push orders immediately to suppliers.  Purchase was not a great experience, however, USPS got it right.  Unit has been installed for over a week and it seems to work fine, hence final rating of four stars.. I know you want seller/shipping feedback through different channel, but customers experiences are total and not by department, so forward if you want.
