Title: Inferior quality
Review: I had this just over a year when I experienced what another reviewer had stated, that the unit conks out routinely after about 15 minutes of use, displaying an F1 or F2 error message. When you need a heating pad, this is more than annoying. I use it for severe arthritis pain and just to move about to unplug it, replug it, start it again is painful. I just want a simple heating pad that works like the older style ones. I don't need any fancy digital controls, just a solid and simple mechanism. Frankly, I think we've farmed out so many of our electronic products to China (which this one is), that we don't have any control of the quality, like UL (Underwriter Laboratories) listings which once told us they were tested and passed specific safety, electrical and durability testing. I think the Chinese equivalent is pronounced (You Err) listing, that just makes sense.
