Divided in the middle Not for glasses with plastic lenses, use basket stupid

In the instructions to the unit:
Not use for glasses with plastic lenses! Coating may come off.
In addition, the bridge in the center of the basket used is so high that I had to unscrew the strap of my glasses.
Very practical!

Habs returned.
2 stars there for the detachable water tank.

**** January 2015 ****
Hab now bought a good device at Optiker Fielmann in the store, for less than 20 euros.
Works, full basket of fully sufficient for all spectacles.
The optician said: ultrasound damages the coating glasses maximum when used daily. If you clean every 2 weeks, nothing happens.
