Customers who have problems with the power cord for the HAI Convertable Ceramic Flat Iron or for any flat iron often have one thing in common: They tightly wrap the power cord around their flat iron prior to placing them away. This improper method of storage will severely damage a power cord for any product. To avoid damaging the power cord, do not wrap the cord around your flat iron. Instead, store the cord loosely coiled.
Once this change in habbit was made, I never saw another problem with a power cord again.
