Initially, the (not purchased from Amazon) has device works acceptable although the temperature already at the top of the rational was (at 43-44 ° C). After 4 months, the yoghurt maker, however, is useless, because it now heated to around 52-53 ° C, and which survives no yogurt culture. Maybe the thermostat is dying a slow death, and obviously not just in my machine, as suggested by some other reviews. The total Komfortlosigkeit I would have accepted (for 3 * it would have been enough), but as the Severin in my view is not recommended.
