The toothbrush holder is great, no-frills, easy, simple, good.
The Klobürstenhalter is unfortunately similar to the soap dispenser provided with a plastic handle. Unfortunately, the standard IKEA do not fit 89 cents toilet brushes in the holder (wobbles) for replacement, it is then difficult. The brush is easy round, at no extra brush for "under-the-edge" have to consider what you want to have. For the current price of around 30, - actually too expensive.
