Yep, I too bought the SmartLife 1500 - two of them in fact. Same story as the others...Problem started with the "E1" code. Now, it runs for awhile then shuts off. It doesn't even give the "E1" code anymore. It just shuts off, and Will NOT come back on, until it sits for a few minutes. It then "beeps" (I guess to tell me it's "ready" to go back to work), and the LED over the "Power" button illuminates. Then it WILL come back on, but it only runs for a few minutes (maybe 5 - 10 minutes), before shutting off again. It appears to me that this is an overheating issue. I've noticed that if I leave it off for several hours (presumably long enough for it to cool down completely), it stays "on" longer, but it still shuts off after about 20 minutes of running. Sure wish I'd known about all these other peoples' problems before I spent my money on this piece of crap. All I can say is don't waste your money! If you want an "auxillary" source of heat, you're better off with an extra layer of clothes!
Oh, and I will GLADLY participate in a "class action" lawsuit if anyone wants to get one started!
