Query: Was adequate when it worked (failed within 6 months of use)

I bought this back in April 2006, but didn't actually start to use it until maybe Oct 2006 when it got truly cold at night. (I would use it under my blankets on the low setting as a footwarmer. :). At that time I was satisfied with the performance considering the low price. I did not like that any radio plugged into a socket/outlet "close" to the socket the pad was using would get periodic bursts of noise from the heating pad's controller, but I learned to live with that.However, back in February the pad started working only intermittently for me. At the moment I can't get it to warm up for me at all so it may be completely dead. My guess is that some of the internal heating element wiring of the pad eventually broke from just normal usage. I can live with cheap so long as it works for me. Sadly, my experience was that this heating pad failed even that very minimal test.-john
