The unit is quiet and seems really safe, compared to other space heater. It ultimately heats up a space, but the way it blows air makes it seems like it's cooling at times. Performance It definitely warms up a space. Ease of Use The unit is super easy to use, right out of the box. The remote control makes it even easier. One complaint is that the remote is so small, it's easy to misplace. The unit has very few settings, and the controls are intuitive. Durability Seems very stable and durable. No issues with breakage and we've had it several months. Design It's an attractive design. It won't blend in with surroundings though, but it doesn't look cheap. Safety This SEEMS far safer than most space heaters. Some space heaters seem to overheat. That has never happened with this unit. Some heaters have visible hot wires - not so with this unit. I would feel comfortable napping with this unit on, and I can't say the same about other space heaters.
