Based on the other "glowing" reviews of this product, maybe I got a bad one. Three major problems:- The Instastart ignition works only about 1 in 20 times. By the time it decides to work, the globe is full of propane, and the lantern explodes when it ignites.- The lantern makes an *extremely* loud humming noise when on low, like a musical instrument. When turned up, the humming stops, and the (expected) hissing sound can be heard.- The knob to control the propane flow is far too flimsy and loose for a product that uses an inflammable substance. It spins around freely like a roulette wheel. This is a serious design flaw.The way I received it, this product is *extremely dangerous*. I expect more from Coleman. I returned for a refund.YMMV.
