I have used this heater for over a year. While it is okay, I am ultimately disappointed. Given the cost, I would choose a different Vornado and likely will. My complaints are as follows: poor temperature sensing and auto on/off, noise, and interface.
The biggest drag with this is how poorly it manages on/off functions. You set a temperature and it turns on. It keeps going well above that temperature, which is potentially fine. It stops, then a few seconds later, it starts again. It continually cycles around this way, which is somewhat strange and unpleasant. This is made more annoying by my next point: the noise.
I have a Vornado fan. It is awesome. It has a continuously adjustable fan speed and it is quiet and smooth. This heater is quite loud and has a bit of a rattle. It is enough to be somewhat distracting. Couple this its deeply annoying cycling of turning on and turning off and the thing is not pleasant to have in the room.
The interface on this is also not great. The controls do not always respond to touch and the unit insists upon spinning up for 20 seconds when you turn it off. It will do this even if it has not been running for some time. It is not awesome.
All these things sum to a less than pleasant experience. While not shockingly expensive, it is not cheap and should be better for the money.
Okay, what did I like? It looks nice and is not very large. It does manage to heat the room and does so with reasonable efficiency. It does not smell funny when running and has been reliable. I am going to look into another Vornado heater that is a bit larger and more conventional. Hopefully, it will be quieter.
