I have had two ionics poles and two gardiners poles.
My ionics grafter had three broken clamps in the first month and they literally twisted off with just slight pressure .
no problems with the glyder carbon pole (apart from being heavy and bendy)
not had a single broken clamp or clamp come unglued on either of my gardiners poles , and my 18ft clx has been properly abused.
yes there are niggly problems sometimes , like the push fit fittings letting go of the hose too easily when you snag but they are easily the best poles and very good customer service.
The Grafter (when they were first released) used the sticky foamy adhesive. Crap.
They sorted that after the first run from what I saw.
Someone I knew had one when they first came out with that adhesive.
I got one 4 or 5 months later, completely different adhesive. Really good actually.
Early days for my Gardiners so I can't pass comment yet.
I've been WFP for 10 years and never broken a clamp (other than wearing down so need to be replaced) I can't work out how guys are breaking them...?
