Bests & Worsts Reviews from Amazon

I bought one and I liked it so much I ordered a second one the same week. I've been running it a bit more than a month and so far it's been awesome. I previously had 3 Germ Guardian air filters, 2 Vornado tower fans, and 1 Vornado space heater. I replaced all of them with two of these Dyson fans and reclaimed SO MUCH space in my apartment. They fit nicely on top of a dresser or in a hallway. The space savings and cable management alone is worth it but the Dyson fanning, filtering, and heating beat out the old gear in every category. I turned off the wifi feature and I don't use the app at all, so I can't comment on those bits. But I did appreciate that YOU CAN TURN OFF THE WIFI so your fan does not join a mirai botnet or try to blackmail you. Top features so far: - Heats a small bedroom in about 10 minutes - Prevented my wife from getting dust allergies when cleaning (she even commented on this to me) - Wife doesn't complain about the fan noise (she did with the Vornado fans) - Night mode makes the display dim enough to sleep next to I was curious how much running this 24/7 would cost me so I hooked up a P3 P4400 Kill A Watt Electricity Usage Monitor. On fan 5 (medium) it uses just 14 watts -- less than a light bulb. When I turned on the heater it used a whopping 1400 watts! That's 100 times the fan 5 setting! Watch out for that electric bill if you use the heater frequently. In my area running the fan 24/7 at speed 5 costs me about $2/month. Running the heater for 8 hours costs me $2.50. Here's a table of the measurements I took: - Fan 5 + heater 1350W - Fan 10 43W - Fan 9 35W - Fan 8 28W - Fan 7 22.5W - Fan 6 18W - Fan 5 14W - Fan 4 11W - Fan 3 8.5W - Fan 2 6.5W - Fan 1 5.5W
