The base and iron combine to a harmonic, form-fitting design. They securely attach to each other via the interlocking SecureLock system–affixing the iron to the base in one step, so it can be moved without separating from the base. Its advanced technology is demonstrated by having only four push buttons for all settings on the base. A one-fits-all fabrics program eliminates presorting and irons everything perfectly (I-Temp Advance.) A 3600 visible red surface light indicates if the desired ironing temperature is reached. The seamless, ergonomic design illustrates the irons ease-of use.
