The full version of these videos can be found on my channel page.

These closers are doing great, although sometimes the left door has trouble latching. The door mags are nice, but this is the only one of the 4 sets to the upstairs/downstairs that has door mags. You have to love the hiss from the LCN 4110 series! The sliding rail arm is interesting too.
