The wife and I bought this the last time it was on Woot. It’s definitely a pricey fan and heater unit (and I could not imagine paying full freight) but it really does a nice job keeping things warm.
For heater mode, there isn’t (to my knowledge) a way to just leave it running, so if you want it for white noise, it won’t work; it cycles based on your thermostat setting, which makes a lot of sense, really, since you don’t want to cook yourself. (I suppose you could crank the thermo all the way up and it’ll just stay on, but again, cooking yourself.)
On the flip side, the heat is nice, you don’t get that burnt dust smell, the remote is pretty nice, but the temperature light on the front is a pretty white LED so I had to tape it without covering the remote IR receiver.
Overall, actually quite happy with this purchase. Our bedroom is in the back of the house and it doesn’t make sense to heat the entire place at night when we’re just in the bedroom, so I was able to save significantly on heating bills since this can keep things plenty toasty.
I’ve used it in cool mode as well (which is, as others have noted, JUST a fan, NOT an actual AC). Getting there by setting the temperature all the way to the bottom is kinda dumb, but I guess it was an easy way to make it “simple”. Once you’re there, the fan does what it suggests.
It’s also quite flexible in how it points, and though it doesn’t feel like the air is quite as powerful as some of the bigger turbo fans I’ve had, it ends up being even more effective since it’s such a wide blast of air. (It’s also actually quite powerful, and quite noisy.)
