I ordered this as a Abflußsieb zuert appointed "No Nameprodunkt" Although the number rather than one contained in the package, was so sharp and bad and even processing section Dangerous so I uneingesetzt sent them back. This WMF sieve is optically at least handled properly and clean. The price, as you can now argue, he is ec stamped from stainless steel and clean. but certainly also in the Far East or something and if nothing had deserved it ... but nungut, you buy it only a time. NEGATIVE: Yes, there are also negative. It goes as it is written fine in the shower but it backs up the water slightly (even without hair in it!) And the flow away the lather remains in the shower tray and makes it partly non dangerous, so 2x happens that our child has slipped. A second have ordered for the sink which we save for Porto, could not be used as the standard diameter of 40mm what a sink drain nunmal so has, the screen can not be sit deep enough so it is not a tight seal on the edge but inside sits on basket and so hair ec. arrive at the edge in the drain and will not be offset in the middle and ergo not have the desired effect. A "press" ec. brought no effect, except that it is now visually unattractive ;-)
Conclusion: yes shower, washbasin and no backlog due & the resulting risk of slipping and because it did not fit into the sink there are only 3 out of 5 stars.
