This is a handy little portable steamer that stays on as long as it is plugged in & the switch is on- and that is one of its flaws. It should have an auto shut off in the absence of water. If you don't shut it off or unplug it when the water is gone, it will burn out. It doesn't hold much water, so you have to be alert-can't get carried away chasing those wrinkles! I wish it held more water so I didn't have to stop, turn it off, add more water, turn it on, wait 90 seconds, steam for a few minutes, stop, repeat above...other than those two issues, it's worthy of 4.5 stars!
