Sizekick können wir nur empfehlen. Super easy im Shopify Shop zu integrieren. Das Einpflegen der Daten ging auch ganz unkompliziert und schnell. Wird von vielen Käufern gerne als Größen-Beratungsinstrument genutzt. Der Support (ein echter Mensch!) hat uns begeistert.

Really happy with Size Kick so far. David helped us onboard and get everything set up across the store smoothly, he was genuinely helpful throughout. The integration was quick, and being able to set up different size guides for individual products has been a big plus for us. Since getting it up and running, we've actually seen our returns come down. Would recommend.

Wir sind sehr zufrieden mit Sizekick. Seit der Integration ist unsere Retourenquote spürbar gesunken, und der Größenfinder wird von unseren Kunden sehr häufig genutzt. Das Tool ist einfach zu implementieren, benutzerfreundlich und liefert zuverlässige Größenempfehlungen. Auch die Zusammenarbeit mit dem Team verlief jederzeit professionell und unkompliziert. Klare Empfehlung für alle Online-Shops,...

Großes Kompliment an das Sizekick-Team! Ein super Tool, das von unseren Kunden überragend angenommen wird und uns wahnsinnig weiterhilft. Dazu ein schlanker Onboarding-Prozess und ein richtig guter Support, bei allen möglichen Fragestellungen. Weiter so & falls es in meiner Bewertung nicht ganz rauskam: Absolute Empfehlung!
