do not fit into any pool

I wanted with this Proften beautify the bathrooms of our three privten apartments, especially as the old but already are getting old .... But the plugs do not fit and can not be adjusted! For older sink therefore totally unsuitable. Even at home, we could then use one of the plugs only a sink in the new bathroom of our daughters. Our other also older sinks also require significantly longer grafting, as they would otherwise be permanent. Even with the longest possible setting they are still much too short.
