Super optics ... in use well

The selection of quality brands sell the glass kettle are very low, so I decided because you can already expect quality for the WMF.

Visually see the kettle from super and so far after 4 weeks I use also may find no fault with the optics.

BUT is on the front of the opening, a plastic filter used the constantly slipping out. And when that happens, the water flows when tilted in all directions. Initially has me totally annoyed because I did not know where it came from and I thought that it with a WMF device must be well thought.

Since this problem annoys me again, I can not forgive no more than 3 stars.
