Never had any problems.
30ft & 18ft fibreglass lasted 3 yrs, 1 x 30ft is still going.
Had 2 60ft carbons, probably heavier than some that are advertised but as with all the poles I've had off them, built to last.
They got a 's' shape gooseneck that screws straight into vikan brushes, but I'm sure they will fit the end piece that you need.
