Here is another hint with your thermacell. Turn it ON and let it sit for about TWO minutes then press the igniter button. I have handed mine to guys, they turn it on and click that button like hell. It needs to get the propane flowing. Also look down the end of it and when you see it start to glow it is lit. You will also hear a little "pop" when it ignites. DO NOT leave one running in your truck by your windshield. It stains the crap out of the glass.
