I was on the fence about purchasing this space heater because I kept reading about mediocre heat output and the heater being noisy. Glad I made the jump and purchased this because the Vornado Velocity 5R is OUTSTANDING. I'd like to address a few things I've read in negative reviews...1. Noise. On low heat, the noise is negligible; it's no louder than any other space heater I've owned. On high heat, the fan does crank up, and obviously puts out more noise. But even on high, it's about 42 decibels (which I confirmed with Vornado support) which isn't -that- loud. I read reviews, "Oh, I can't even watch TV with this thing on it's so loud!!!!" That's so hyperbolic. It's not anywhere near as loud as some of the reviews make it out to be. And again, on low heat, it's relatively quiet.2. Heat output. I've seen a few reviews complain about the heat output or even state that this thing just pushes out lukewarm air. I completely disagree -- this heater pushes out a TON of heat. I think some of these reviews had it on fan-only mode and didn't realize it or maybe their unit was defective. Either way, pay no mind to the reviews that are critical of this heater's heat output. I've owned a dozen or so space heaters from different brands during my lifetime and I'm very impressed with the unit's heating capabilities.3. Get the Velocity 3R. The 3R has the same heating specs and wattage as the Velocity 5R, and I feel the extra features included in the 5R (like the cord storage compartment) don't justify the increased price. The auto climate feature on the 5R isn't really that great; I don't even use it. If money isn't an issue for you, then sure, get the 5R. But for most people, the 3R is going to be more than fine.Overall, a great product with some nice features and safety features. I wish that the 5R had a bit more to offer over the 3R, but I'm still comfortable giving it five stars.**NOTE ON THE AUTO CLIMATE** This heater dynamically adjusts the temperature of the heat based on what the thermostat is set to. Just crank it all the way up to a maximum of 90 and this will ensure that the heater is always producing the hottest air possible. I think some people don't do this and this is why that they claim that the heater only produces "lukewarm air"
