The exceed pole has an oring in the place that Gardiners have the spring I assume to act in the same way so the clamp can adjust to pole wear. Wether it is as good only time will tell

Hi Lee,
the o-ring, was to help with resistance, to help the bolt not come loose, but as In tlwcs case, the thumb adjustment still came loose, causing the handle to flop.
thankfully we have cracked it.
we tried locking nuts that stopped this but you could not turn the thumb wheel by hand as it was to tight.
but now we have found a nut that stops the handle coming loose but easy enough to turn.
I have contacted tlwcs, and said I will send him these locking nuts for free.
as regards aqua dapter not working 100%, we are going to harden the spring.
To be honest we only designed the aqua dapter for 18 to 25ft poles, that are everyday, and constantly extended up and down, so your able to save water between, these stages.
as standard now, we fit a flow valve at the brush head, with the aqua dapter as another option.
