Bests & Worsts Reviews from Amazon

This is probably only the second or third time I've ever reviewed a product on Amazon (I'm lazy), but I had a very scary experience with this mattress pad this morning, and I feel compelled to post this. I bought this in October 2015, used it the winter of 2015-16, removed it in spring 2016, washed it per the instructions and stored it over the summer. I put it back on in probably November 2016 and have been using it most nights since. I'm leery of the whole idea of electric warming things, so I use the pad only to heat the bed before I get into it, then turn it off once I've been in the bed reading or watching TV for 10-15 minutes. The pad has not been heating the bed as well as it did last year, but it was ok. Once this past fall I was standing in my bare feel next to the controller for the side of the bed I do not sleep on. I noticed that the floor (hardwood) felt damp. I touched it with my hand and there was a small pool of sticky colorless fluid, and I noticed that the top of the controller had some white crusty stuff on it. I thought maybe my cleaning lady had run over it with a mop or something. This happened one or two other times as well, the same small amount of sticky liquid, even when my cleaning lady had not been there recently. This is did not happen to the other controller, which is the one closer to the plug and was on the floor on the side of the bed I sleep on.So--last night it was unseasonably warm here in Connecticut and I didn't bother to turn on the pad before getting into bed. This morning I was lying there after having hit the snooze button a couple of times and I noticed a smell that seemed like burning plastic. I was half asleep and thought I was imagining it. I kept getting whiffs of it and it seemed like it was getting stronger. I finally got up and started sniffing around the bed.I confirmed that the controller on my side of the bed was off. When I got to other side of the bed, I saw that that side too was off, but I picked it up anyway. It was so hot I dropped it immediately. There was again a pool of sticky colorless fluid on the floor, and I got down and sniffed it--yup, that was it. It must be melted plastic. The top of the controller was now completely covered with the crusty crap I'd noticed last fall. I ran over to the other side of the bed and pulled the plug out of the wall--it was plugged directly into a grounded wall socket. I unplugged the controls and put them outside on my deck, where they're still sitting. I've attached a couple of photos. That's not bad housekeeping--the other controller still looks brand new. It's now 12 hours later, and my right hand still smells like the melted plastic, even after a shower and washing my hands 3 or 4 times today. Based on what I've seen in other reviews about the customer service experience, I'm not even going to try to get in touch with Sunbeam. I'm just going to count myself as lucky--I don't know how much longer it would have been until it ignited. No other (one-star) reviews report an incident like this, so maybe this is just a freak thing. But no more electric bed warming for me--I'm stocking up on hot water bottles.
