Bests & Worsts Reviews from Amazon

This is a great little device but it's important to understand a few things. I wrote this review because I saw some high marks and some low, and I wanted to try to explain why there may be such a difference. It's all about using it in the right conditions. Check your local weather. The lower the humidity in your home / area, the better. If you have a nest or other smart thermostat, you can check the humidity level in your home, which is even better. If you're 60% humidity or higher, it probably won't work well. 40% or lower, and it will work very well. 40%-60% you'll get some minor cooling action. 1- it is a swamp cooler. It's not a new concept - they've existed before air conditioners, but if you're not familiar with them, do a quick search and spend some time reading about it. I'll note - there are many cheaper ones on Amazon that may work just as well, but this only appeared to be much higher quality and looks like it could almost be an Apple product. 2-if you did you research, you'll see that they're only effective in hot and dry environments - so good for desert or Mediterranean climates, which is the US is mostly in the South West. In hot humid environments, it can actually make you feel hotter, by adding additional humidity to the air, and the cooling affect is mitigated. 3-this is a personal cooling device, meaning you'l only notice it if it's blowing directly on you, it it not going to cool a room unless you're standing in a closet! Keep in mind, it uses less energy than a light bulb and is powered by a USB cord - so don't expect it to work like an AC. The laws of physics are still in play - cooling air takes a lot of energy. This unit uses 7.5 watts, of about 10% of what a light bulb uses, an AC may use 1200 watts. The benefit here is that it costs virtually nothing to run and does not require a vented exhaust, like as AC unit. On it's lowest speed, it is also nearly quiet, but it is a bit louder than idea when on high. 4-with that said, if you do live in a warm and dry climate, it works nicely. I work from home and find that if I keep it blowing on me directly during the day, I don't need to pay to cool my entire house, or I can at least turn up the thermostat to 78-80, and still feel like it is 72. This allows me to easily justify the cost of this little cube, even at $100. 5-pay attention to the dimensions - it's about half the size of a show box, so again, don't expect this to cool a bed room.
