Testimonials

After a long time working as a warehouse worker, I struggled a lot with joint pain and first came into contact with cold therapy through my sports medicine doctor after medication no longer helped. Although I was skeptical at first, I really have to say that to date it has been the only treatment that has helped me. I’ve now treated myself to a Winthera Flex including the Ice Master Light and I am almost pain-free. I’m very optimistic. The main complaints in my wrist have disappeared. The products are truly excellent and very high quality. Simply top-notch. I can recommend them 100%. If you want to start with cold therapy, I can only point you to Winthera’s products. They know what they’re doing.

Friendly contact and good service. I am extremely satisfied with the winthera flex after having had bad experiences with cheap AMZ products in the past.

As a certified Wim Hof Method Instructor, I have tested many different Icetubes. But Winthera was the best, very high quality and solid. It comes in a compact backpack easy for transport. Very easy to enter and exit, great for all ages. It cools down your water till 3°C what allows you to have a nice cold plunge in summer timer too!

I recently purchased the Winthera Flex Ice Bath along with the Ice Master Light chiller and I’m really happy with it. The setup was surprisingly easy. Took 30 min with electric pump and hose. The bath itself is lightweight and very portable. I’ve already moved it around my backyard multiple times by myself. The chiller is almost silent. I like my ice bath at 4 degrees and before my girlfriend joins me I set it to 12 degrees. Very convenient! I have used cold therapy regularly in the past and I’m really impressed with the quality for the price.
