The NO NAG takes the guess work out of knowing how much gas you’ve got left in your gas bottle, so you’ll never be nagged again about ruining the BBQ, or not swapping the bottle when you had the chance again.
Unlike other similar products on the market:
This is how it works: you move the marker on the gauge to the empty bottle weight, which is marked on the side of the bottle. You move a sliding ring up to the marker, attach NO NAG to the bottle and lift it off the ground – 25mm off the ground is ample. Then you remove NO NAG from the bottle and view the results. The sliding ring will have moved to indicate the amount of gas remaining. It’s as simple as that.
