Just installed these yesterday. It took about a total of 12 hours to complete. 7 hours for the curtain rod install and adjustments, 1 hour to install the Logitech Harmony Hub (mainly because it froze at 90% installing firmware update so had to factory reset and start over a couple of times), and then 4 hours to mess with the really bizarre way that Harmony must use "activities" instead of just sending IR command without anything else.
