Preliminary a short note: was included in my case a grid insert made of plastic, this I would therefore not need to be ordered separately. However Practical additional accessory is a glass grippers to lift the Weck jars from the hot water. The pot is working properly, the cooking time is running once the exact Chill is achieved. Unfortunately sounds after the time no sound. One should therefore also provide an alarm clock / timer when the correct temparature is reached, so you do not miss the right moment in longer Einkochvorgängen. As long as the pot is in operation, the red lamp on the front, it will not turn off when the temparature is reached. Inside the preserving coated with enamel, processed everything neat and even after several operations perfectly. It settles over time lime that can be wipe with vinegar water. The plastic lid is not quite as high and closes with me not fixed completely, but it is for the price absolutely have to be accepted and not affected the result negatively. All in all a great device and thus preserved foods have already fully met our expectations. Good value for money.
