During the development phase and beyond, our products undergo intensive testing by market test customers and are exposed to rigorous real-world conditions. We would like to invite you to join our group of market testers. Here are the benefits you'll enjoy:

• The opportunity to use/ test products that are not yet available for purchase, free of charge.
• Optional participation in expert panels (with separate compensation).
• Your feedback contributes to optimizing our products.

Register your purchased device and yourself to receive 5 bottles of Renfert Descaler (descaling solution) for free as a token of our appreciation for your registration! We will contact you separately thereafter.
