Hi,
I haven't had a chance to touch and try the new hoses yet. I will try to do that asap, because: I know a couple of people who already use the new hoses and everyone basically says the same: compared to the old hose it's like night and day. So much smoother when running over edges, so much more flexible, thus easier to handle/maneuver ... (And I never had any problems with my old ones, except for the occasional snagging on an edge...)
I'm pretty sure already that once I tried them, I will get the new hose(s), too.
Personally I won't sell my old because it's always great to have a "free" emergency replacement at hand - but that's just me. And given that even the old hoses still fetch a fair amount of money I can see how some people want to recoup some of the expenses for the new hose.
However, if there should be a CTL-SYS coming with the Bluetooth functionality, I might sell my current unit depending on market price. If I deem it too low, I will find a use for it without much trouble.
Kind regards,
Oliver
