Ive had my extreme 25 a year and its battered.
I snapped section 2 a few weeks ago to add to section 1 that went after a month lol
It looks 3 years old, its a great pole though.
Ive had a nano 18 since last nov, its wearing a lot better but then its not been used nearly as much. 3 things annoyed me with the nano. 1, its not as smooth to extend as the xtreme it has to be pulled out, secondly the clamps aren`t as nice to use. Now it has freed off a bit and as im getting used to the clamps its a lot more tolerable. But the one thing that drives me nuts is if you extend the sections fully them Jam. I have to bang the bottom section on the floor to collapse it, now if im carefull not to fully extend its fine but it always happens once or twice a day and its really annoying. Given that the extreme is in such bad shape after a year i might get a nano 25 to replace it when black friday rolls around again, will see if the 18 grows on me first.
