Review: Good for what it does. - These are pretty accurate if you need to take a quick ballpark measurement and don't have the time to work a more precise device. You ABSOLUTELY need to "season the needle" by soaking it in 35ppt salinity water. Before I seasoned it, the needle showed 1ppt higher reading, which is probably why some people think it's inaccurate. The scale marking are excellent, actually and they even put in a bubble remover on the intake.
Review: Reliable - Works as expected easy to read and pretty strong

I compared this with my LFS digital tester and it is Accurate. Right out of the package it is not accurate but follow the directions and season as instructed and you will have an accurate budget tester.
