Reviews on our website can only be submitted by customers with a registered user account and only for products that they have actually purchased from us. The rating function is therefore only activated after a purchase has been made.

Checking mechanisms

Manual Review:
Every incoming evaluation is manually sifted and checked by us. In doing so, we check the content of the evaluation for logical inconsistencies and other conspicuous features, among other things.

Customer-Initiated Review:
Every visitor of our website has the possibility to report conspicuous ratings to us via e-mail to with optional naming of reasons.

Manual spot checking:
According to the same standards, we also carry out random checks of individual comments that have not yet been pre-filtered elsewhere.

As soon as an assessment contains anomalies based on our review mechanisms, a detailed manual review of the respective individual cases follows.

All evaluations filtered out or reported in this way are both checked by our team against our evaluation guideline and subjected to a general plausibility check.

For the plausibility check, we consider the entire rating behavior of the customer and also take a look at the content and metadata (e.g. IP address, device ID, date) of the rating. Here we check whether the acquisition and valuation of the product are in temporal and spatial relation to each other and whether there are contradictions in content. In this way, we address the question of whether the customer has actually used the product.

We then try to contact the authors of such conspicuous ratings in order to verify the statements in their ratings if necessary. If the circumstances clarify, the assessment will be adjusted accordingly and published. If the circumstances for the rating submission remain too vague and unclear, the corresponding rating remains filtered out. It will not be further displayed or even published.

All ratings filtered out in this way are not included in the overall rating presented.

There is no stricter filtering of negative ratings or preference for positive ratings. As long as an evaluation meets the above criteria, it will be published on an equal footing regardless of whether it is formulated favorably, critically or even pejoratively.
