The 7.63-inch tall Dabcool W2 features a fast 20-second heat-up time and offers 4 temperature settings (450℉/500℉/600℉/680℉). This compact rig is constructed of metal and rubber and has a grip on the bottom so the unit doesn't move, scoot, or wobble during use. 

The W2 operates via one button on the front. Press the power button twice to heat the unit up, then press it once to toggle through the 4 heat settings. One blue light illuminates for 450°F, two blue lights indicate 500°F, three blue lights are 600°F, and four blue lights are 680°F.
