What I like about this model: all connecting parts (coupling and plug) are visible and seem "bomb-proof" to sit on the cable; the risk of unintentional demolition when connected to the leads I stage - in contrast to the "tube solutions" other providers - as rather low, because all the components are open to view. The cable itself makes a massive impression, which prevents the emergence of the closing of windows / doors pressures well. It is extremely supple and pliable.
The open "unverschnörkelte" design allows it appears desirable, the cable does not hang in the horizontal area of the lower window / door edge, where it is exposed to strong surface pressure when opening and closing the window / door with the risk of increased wear, but rather in vertical area where only occasionally the window / door is on the cable.
My experience so far (as of 24.04.2014) are positive; I'll nachberichten.
