Well it lasted just over a month.. II just stopped working tonight. I used it daily because of the "Polar Vortex" we had here in the Midwest. It was great and tonight it just stopped working. Going to see if I can get my money back. VERY DISAPPOINTED.
The first one of these I purchased stopped working in less than a month. Thankfully, the people at Overstock initiated an immediate replacement. I just received the second one, so I really can't say anything about how long it will last. Hopefully, it will be a long time! In general, it is an attractive heater. I have three heaters of this style in my home, and I must say that this one has the most attractive and realistic-looking flame effect of any of them. It has a low and high heat setting, and heats my office very quickly. It also has a setting where you can have just the flame effect and no heat, which is really nice for ambiance on days that are already warm. So, as long as this replacement heater keeps working, I recommend the product. If it is a dud like the first one, then I would say to stay away!
