Yeah, but you put an unger rubber in an ettore channel and it’s enough to make you wax a g in the dome straight black and decker.
(Sorry, I had to go to Espanola today so I was diggin the 90’s gangsta rap.)
Unger rubbers are a millimeter shorter than ettore and it’ll straight jack with your flow. Seriously, I thought I was going insane in the membrane and totally lost all ability to clean a window with that unger mess.
If ettore doesn’t get their stuff straight (it’s been over a year now), then my go to rubber will be pulex. I didn’t really care for the professional rubber, but I’ve got a few just as backups for the backup. After that, I’ve got some 7 year old 3 star laying around somewhere.
