Bests & Worsts Reviews from Amazon

Do not buy this product. Not that the product doesn't do what it says it's going to do, but there's a bit of physics about a PROPANE tank gauge or any gauge that reads the pressure of a cylinder with a gas and liquid phase present. Propane is in the liquid phase and as long as there is ANY liquid in the tank, the pressure will be constant. The pressure on the gauge or in the tank does not decline until ALL OF THE LIQUID PROPANE is gone. This means that this gauge will read FULL until all of the liquid has been depleted and will not begin to decline until there is only gas left in the tank. Basically, due to physics and no fault of the product (but a little deception by the manufacturer), the reading on the gauge will not drop until you have only a few minutes of propane left in the tank.
