I bought 3 of these during the end of winter. It seemed like the temperatures were really inconsistent, and I'd be spending one day warming my house with the radiators and the next trying to cool off! They are perfect little heater fans. They produce some white noise, which helped my kiddos sleep. They don't dry out the air and 1 is enough to heat up my entire master bed and bath together. Perfect for reducing heating/cooling costs during those seasons where it's all over the board. It's been about 6 months of intermittent use and they show no signs of wear. Best part is they don't get too hot so I can leave them running when the toddler is about without worrying about burns.
