Been hammering the crap out of a switch nitro for a couple of seasons in the surf, still looking like new, no repairs as yet, touch wood.

Also fly ozones, the switch has well out lasted the ozone in the fading and wearing out department. Both kites are good and love riding them though, one has just out lasted the other.
But you cant blame shop guy for trying to bag out a kite that is half the price new of what he is selling at his shop. It was always going to piss the shop guys off losing business to internet sales of gear as good, if not better, quality that they cant compete with.
As for the nitro3, havent tried it yet but one of the locals here just picked one up and is raving about it,, cant wait to take it for a spin.
