What marketing and brand managers say

"We were pleasantly surprised by the professional approach, quick and smooth negotiations and perfect results of the campaign. Thanks to this cooperation, we received high quality reviews for our products across e-shops and social networks... "
Tereza Límová
Digital Manager - Henkel Beauty Care CZ/SK

"Thanks to testing on the zenysro.cz community, we were able to target new potential customers who responded to the vouchers with a 95% success rate. We benefited greatly from feedback on the range breadth, speed of delivery and price of shipping directly from female consumers, who gained new experience and gave us new suggestions. We also appreciated the speed with which the campaign was approached and the feedback and reviews provided on the eshop and price comparison site."
Vladimír Finsterle
General manager lekarna.cz

"Advertising is impressive, but what people say about your product is much more important. Credibility is what makes the difference in sales. And that's exactly what you get from Testuj.to. Plus, testing was just the beginning. If we hadn't gotten those first 46 reviews from testers, we would have hardly gotten to where we are now. Testuj.to helped us start the review collection. And we look forward to working together to start more of our products."
Alexandra Melicherová
PR Specialist, NaturaMed Pharmaceuticals

"Testfluencers was created with the idea of bringing an original benefit to our clients and in the end it turned out that this project brings even more to all parties involved. The implemented campaigns confirm that brands not only can gain so many valuable reviews, for example on the first day of sales, but also insight into the customer mindset and increased brand affinity. But this form of collaboration is also extremely beneficial for the influencers themselves, not to mention the engagement of users who really enjoy Testfluencers."
Veronika Zajícová
Influencer Marketing Consultant, Konektor Influencers
"We usually gather the first reviews for a product for quite a long time. Testuj.to accelerated the writing of these reviews for us. It started with reviews from Testuj.to testers, but the next reviews were already from regular customers. That's what makes us even more excited about the collaboration, because we're still benefiting from it even after the project is over. I was intrigued by the range of their testers and the fact that the entire testing process is handled by Testuj.to, from sending the products to the testers to delivering the reviews. I always expect 100% from any service and working with Testuj.to was definitely 100%."
Miroslav Šiška
B&C Specialist - Reckitt
"We were worried about the quality of the testers, so that the person knew at least a little bit about technology. Brand Testing Club provided us with assistance in the selection process and, most importantly, 5 times more testers. So we had a lot to choose from. Testing the dashcam was a test project. It went very well and we will continue to test other products with Brand Testing Club. I look forward to further cooperation."
