They look good enough that I, at least in the bathroom (where they fit in color for me) leave lying around openly. The material is strong enough to keep the windows and (balcony) door so quite accurately in the position in which one has brought them and flexible enough to cope with different opening angles of the various windows.
An unpleasant smell of rubber as described in part I could not tell, but maybe my nose is not as sensitive enough.
Whether as a rubber thing must cost necessarily just under 12 Euros now I doubt it, because for me but no shipping costs have been incurred, the stoppers are quite nice to look at and I'll have to buy me this product for a long time nothing new I look at the price more than secondary.
I forgive 5 stars because I think the price / performance ratio for a total of more consistent, especially as the supply for Prime customers is free. Since the despatch by Amazon there also naturally nothing to complain about in terms of speed / packaging.
