Very easy for us. As others have mentioned, lifting the TT's tongue with the electric jack means I can do both ways without using a wrench. You'll see a similar tip (of lifting the tongue) for almost all other WDH systems.
I've added a P-touch label onto the custom socket they give you with a 3-4 turns reminder (and it gives me a spot to count the turns).
One of the big benefits for me is my wife can get our TT hooked up before I get home from work on camping Friday's. I'll have the ball assembly already in the truck, but she'll do the rest.
I have about 4,700 miles of towing with mine in the 1.5 years since we bought it. I suspect it is not putting as much weight back onto the front tires as other systems would, but that's my biggest concern to date.
