fits perfectly, manual is good trick with the oven = Spiralschlauch works

That the hose is good enough people have reported yes. That the hose NO spiral hose is available in the product description. I got the trick with the oven from reviewer LB tried (my oven was still warm from the dinner anyway ...) worked great. With the hair dryer it is certainly, as has described an other reviewer.

The installation goes smoothly when you proceed gently and with common sense. The annexed guide will do just fine, if you will implement it literally (sthet there: "Carefully lift on the side", then you should really on the side, not the front or rear, levers) not for the impatient Grobmotoriker is however. The drawback with the Torx screws can be resolved with a normal, fine screwdriver. (Long it should be and estates very narrow tip have). Again, of course, is a bit of sensitivity needed.

The benefits (no new Dental Center needed) justifies the effort (fumbling) in any case!
