I have an unger s 14inch handle and channel. I have had it for about 15 yrs and it still works. I have from time to time changed the rubber bit, I used to change it weekly, flipping it over on a wednesday afternoon. I now use wfp so one rubber can last for several months. I have always used cheap pulex rubbers and never had a problem with them or unger. Don't knock unger they make good quality tools that last.
