After contacting Isosteel asked me a desk officer, Mr. Herold, so send him with the product. Very swiftly us a new cup was delivered. Then Mr. Herold replaced us even the shipping cost incurred by us.
Our warranty was handled very professional, swift and very friendly.
Thank you for great thermo and a company that cares about its customers!
Isosteel anytime.
