In the run-up to the test, we defined practical requirements and the following test criteria:
- Popcorn quantity
In order to be able to evaluate these criteria, we have defined several tests for the popcorn machines. First, the scope of delivery is checked and the devices are prepared according to the manufacturer's specifications. In order to be able to compare the machines better with each other, about 30 g of corn is filled into each machine. When the machines are in operation, the time required is stopped and the power consumption is measured. In addition, the temperature of the machines is checked with a thermal imaging camera, among other things to identify potential burn hazards.
In further runs, the popcorn is garnished with salt, sugar, and butter according to the manufacturer's recommendations. During these processes, the machines are checked for handling and user-friendliness. Finally, the cleaning effort is assessed.
In order to rule out errors and to ensure the stress of everyday use, each test takes place in several rounds.
The test criteria are given 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 an 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.
