I highly recommend this unit highly. Unlike most other this device really smells in operation only to warm air and smells a bit. The LCD display is blue and you can regulate the temperature continuously. Unfortunately, the device allows for only 2 speed settings. But what probably is normal in this price range.
The only slight criticism would be that the display always between target and actual temperature jumps back and forth and you know not what is shown. When adjusting the temperature to be displayed. Shortly after that it jumps to the current temperature and you see how it heats.
