It is very helpful to use the Assembly video [...]. The seller sends an appropriate link on request. The supplied installation instructions tried to get along without text - to ultimately accompwished assembly is understood then how the images work might be meant well. If you have to mount several pleats, one could not 10 minutes might create with it-adjusting the exercise referred to in some reviews * assembly time, the first time with certainty. Especially as marked on the pleated assembly arrows lead you astray, like other reviewers, we had to assemble directed counter to the direction indicated by the arrows down the pleats. Perhaps it comes with the fix clamping * * variant faster (parts therefor must be ordered separately!). But if you screw each of the four mounting points must pre-drill before, it takes longer for sure. The screws are incidentally extremely long, for wooden windows certainly exaggerated. A good tip is (see video!) To produce the necessary tension on the last upper mounting point to a node in the Schur. Cutting last! The pleated itself certainly has good value for money, so we can be satisfied. All white, it is the way not a little yellow shade you need to schedule here. And the whole wide version 120 cm is also not 175 cm as indicated, but like all the other variants only 130 cm. Conclusion: A good product, but a lack of care in assembly instructions and product description provide point deduction of (at least) a star!
