Received this as a gift about a month ago. Loved it for a month, then it stopped working.  There is perhaps some faint heat coming from wires in the blanket; however, if present it is insufficient to do any good.  Digital display works well so the issue seems to be in the blanket.  As such, it is useless.  I will note that the person gifting the product has one as well; she has used it over time and has been very happy with it.
