The 70o0IS has been designed from the ground up to deliver superior quality dry steam, and provide the best possible user experience. RELIABLE™ understands that the quality of a boiler-iron is only as good (no matter how nice it looks) as what is inside it. This is why we use the best components available; 12-gauge wiring throughout, a ceramic (not plastic) terminal block, Teddington pressure control and an all stainless steel steam tank to eliminate the chance of rust.
