Not the most exciting review, just a small note that we had a port that didn't work. looked a bit rusty and old and the connections didn't look good. it came and was the perfect replacement for the low voltage connection of 20 years ago. These are standard low voltage-only connectors, so I'm guessing they only apply to "pigtail" hoses when you plug a power cord into the wall next to a vacuum connector that only has low-voltage wires connected to it. There is nothing to add. looks great, took 2 minutes to install and works just like everyone else.
