Query: Works great!

This heater works great. It does not shut itself off when jiggled and it has a variable heat dial too. Had bought a heater sold at the golf store but had to take it back. Had to relight it too many times, its emergency shut off made it a frustrating hassle. And it did not come with a nice carrying case like this Coleman model does, and it cost more. This heater is the best Christmas gift I've had in years, finally, something useful!
