In the run-up to the test, we defined practical requirements and the following test criteria:
- Functional scope
In order to evaluate these criteria, we have defined several tests for the ice machines with compressor. These are used to prepare chocolate ice cream in the form of "hard" ice cream and soft ice cream. Before the first use, the machines are prepared and assembled according to the manufacturer's specifications. In addition, the existing functions, such as automatic switch-off, are checked. The required ice cream mixture is made by our testers themselves from the following ingredients: 250 ml milk, 50 g whipped cream, 200 g dark chocolate and 100 g sugar. The finished mixture is put into the machines and the time is topped during the process. Handling, ease of use, power consumption and volume are also assessed during the test series. As soon as the ice cream is ready, it is evaluated by several test persons. If the desired consistency has not been achieved, a run with individual settings is carried out. Finally, the devices are cleaned and tested to ensure that the individual parts are dishwasher-safe.
The user-friendliness and handling are always taken into account. . Other functions are tested in further stages.
In order to rule out errors and to ensure the load of everyday use, each test takes place in several rounds.
The test criteria receive percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.
Our product selection is based on observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.
