Product works reliably. It's slow going up and down, but that's okay.
Service from Aladdin during installation was excellent!
Meeting the requirements for installation was a bit of a challenge. I recommend reading the manual prior to purchase. In my case, I had to relocate the chandelier and ceiling medallion away from a joist, and this required scaffolding plus ceiling repair/painting which added $500 to project cost. As always, it's unpleasant working in an attic. Installation took me a week.
I wish the unit cost $350, rather than $700.
I'm very happy to now have access to my chandelier, plus it impresses guests.
