Meter works Ok once you’ve got it connected. The problem is the rubber tube is too tight to easily fit on the test nipple. It could do with a more flexible tube to easily slide onto the test point

Great backup for the toolkit !

As other reviewers have said. it's about the right price for what it is, but a real shame the tubing isn't at least 15-20cm longer [or more] for ease of use. The "stand" doesn't really work as the tubing is far too short in pratical terms, the gauge works fine. It's super simple to balance with the sliding level marker, so what's not to like ??
