If the plastic latch breaks you're screwed though. I've thought of 3d printing a guard ring to make sure that the lock section can't hit the ground when dropped.
I have one that extends to probably 15 feet that I bought at home depot. Seems solid. Gets so little use I'm sure it will last super long. Takes multiple attachments, very handy.

i've found the Wooster brand of extendable poles at Home Depot to be very well made
