In the run-up to the test, we defined practical requirements and the following test criteria:
- Temperature control
- Overall impression
In order to be able to evaluate these criteria, we have defined several tests for the curling irons. First, the scope of delivery and functions are checked. Before the first test runs are carried out, the required warm-up time is stopped.
We work with the highest temperature level, which is measured first. If the devices have several stages, their temperature is also measured.
The curling irons are used according to the manufacturer's recommendation. Handling, user-friendliness, and ergonomics are evaluated. It is also tested how efficiently the curlers are wound and whether there are any potential safety risks. Finally, the results of the devices are evaluated.
In order to rule out mistakes and to ensure the strain 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.
