In the run-up to the test, we defined practical requirements and the following test criteria:
- Safety and security
- Noise level
- Overall impression
In order to evaluate these criteria, we have defined several tests for the can openers (electrical). In these tests, all devices must open cans of different thicknesses and sizes.
Before the first run, we check how good and ergonomic the devices are in the hand. While the devices open the cans automatically, the required time is stopped and the volume is measured.
It is also checked whether the can openers pose a safety risk during operation. The cleanliness of the cut is assessed on the opened cans and care is taken to ensure that sharp edges are formed. Finally, the equipment is cleaned.
A clean cutting edge greatly reduces the risk of injury.
In order to rule out errors and to ensure the load of everyday use, each test takes place in several runs.
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.
