Now that summers gone

and we are back to the cold and rain that we all love

its not always easy to have the front door open while cleaning.
I spotted this on the Hydramaster web site.
Does anyone use one?
Are they any good?

Door Jam
Ref: AD04
Hoses in... Unwanted Temperatures out! Cold air, hot air, bugs and animals are kept outside where they belong, winter or summer, when you use the DoorJam. All true professionals will now be able to protect the customer's environment and still be able to run hoses through the door. When finished the DoorJam easily rolls into a compact bag for storage.
