Title: The infamous E4 error
Product review: Same as many others - worked for about a week, then got the E4 error. The controller gives a soft but audible click inside when you turn it on, and the display toggles between 'E' and '4'. The on/off button does not turn the controller off at this point. Checked all connections, wiring, etc. but nothing helped.The blanket itself is very soft, but even at the highest setting it never got very hot. A very disappointing purchase.
