not exactly thermostat

the kettle is to use everything good at everything. For the money it is good as more expensive are not necessarily better. I count only the (small) negative points for difficult people:
- The thermostat has only two stages. if one puts him about the mark, he cooks at 100 degrees (bubbly!), even if the pointer is not limited to max. stands!
On how many degrees Celcius in marking the water is brought, is nowhere to be read or seen. For green tea drinkers (water to 80 degrees C) somewhat impractical.
- After about a month in use it smells unfortunately still to plastic! The world can no longer exist without plastic well!
- It is in the instructions, the water should not remain long in it, for example to 1 hour before it is wegzuschütteln (even though it was cooked!). why? no explanation! (Or it may be someone bittte me wisssenschaftlich explain?) Clatronic WKT 3093 Kettle 1.5L
