I purchased two if this model for my two burner model, and they work great! They light the burners every time with one or two clicks. You must follow the instructions, and get the gap correct. Bending about 1/8 of the tip down toward a burner orifice is the key. Don't flood the area with gas before you click. Click as soon as you turn on the gas. If it doesn't light it's probaly flooded. Turn the gas off and fan the area to remove the excess gas, or wait a few minutes until the gas disipates. Then try again. I have had two happy years using mine. I am a retired aircraft maintenace technician, and I see no design or engineering flaw in this product. Happy camping!
