At first the plastic handle is broken out of the metal cover. Contrary to expectations, the grip is additionally screwed but glued. The adhesive is sooner or later by the expansion when heated to dissolve and the parts apart. I have in this regard calculated the replacement unit has a maximum design consequential damages, however, it did get worse.
The second boiler seemed to have gotten more adhesive, but in this, the shutdown has failed. Until I noticed that, around 1 liter of water had evaporated from the digester. It was running out of water in the device, the next step would be to me the kettle burned through - and with it possibly the whole kitchen. In a moderately used device that was only 1/2 year old.
This is simply a no go!
Therefore: clear recommendation to opt for another device.
