I purchased my unger pro squeegees when I started, they are 22yrs old now and the handles cost £2.25 each then. Durring that time Iv'e had to buy 4 new rubber grips for them.
Has anyone had there's longer, and do you think Iv'e had my monnies worth? 
I think at this rate they are going to out last me

Just to make sure that you DO get your moneys worth, maybe you could rent them out to a museum for public display

.
Are you still using the same squeegee rubber after 22 years as well ?
Joking aside, I think one of my squeegee handles has been with me from the start as well (15 years). They're not the sort of things that wear out are they? I guess I would be more likely to lose it.
