TL;DR: All portable electric heaters draw 1500W and gradually circulate air through a room until the ambient temperature matches the internal thermostat. This one just does it cheaper. This model looks sleek, it's very light, the case almost immediately cools down after powering off, and the fan is pretty quiet. It works as intended: 1500W (the highest wattage allowed in the US and a standard with all heating units) is quite hot if you're in front of it, but the unit is pretty small so the amount of cold air it can suck in through the back is going to be small too. It's best used under a desk (where the air is partially trapped between your legs and the \"fireplace\" surrounding the heater) or at face level where you can just feel the heat right away. There are a few additional drawbacks. The safety anti-tip switch is just a short peg, so it's got a hair trigger (uneven surfaces, say like tile or brick, the peg might slip into the grout gap and shut the heater off). There is also no real \"low power\" mode; typically low-power would be ~800W whereas this unit still goes at ~1100W (note that the fan always goes at a consistent speed; the low-power mode just lowers the strength of the heat). And of course any knob-style thermostat is very inaccurate; the lowest the knob goes is like 75° and unless the room is barely bigger than the heater, the ambient temperature will almost never hit that. If you're getting a portable unit, emphasis on portable, this should be your go-to. On high, it can still keep an already room heated. It won't instantly warm up a small room (give it 15 minutes), but it will definitely be great as an under-the-table heater for your feet or an immediate hand warmer after washing vegetables.
