Although does not stink after plastic but has significant deficits

It seems several product variants in the sale to be because my plastic cap does not stink - would be for me as well as an immediate return reason!
However, there are other significant shortcomings of the device:
The device is used with me for about a year in operation and estimated 50-60 times.
The plastic articles (for inhalation additives) are broken and the entire structure is actually made pretty "cheap".
It can be prevented impossible for inhalation additives reach (eg. Camomile extract or oils) in the "pot" and the dirty immediately and can be due to the structure (not waterproof) and clean bad.
The missing shutdown nedrigem water level is also fairly inexpensive and has due to the aforementioned non-shutdown rather unpleasant combustion odors result. Not exactly conducive if you're already caught a cold :)
If at the price not well thought out and high quality product can be manufactured, then you should either be equal to or demand a higher price for something decent. Unfortunately, so far I could find only similar inferior products in this segment. Schade ... Marktlücke - love and Grundig Beurer!
