I haven’t had the opportunity to test the GasWatch yet, so I can’t give you a first-hand account. However, from the video it looks pretty intuitive. The scale is pretty slim, but there might be an issue with a scale-equipped tank fitting in the cabinet under some grills. You might measure that space and do some basic math before jumping in, but I do believe it’s worth considering an investment in one. If nothing else, it will help clean up my garage-based cooking area by reducing the amount of half-filled propane tanks I have around.
