Review on Get Precise Measurements With GemRed XLB Digital Angle Gauge Level (82412-XLB Angle Gauge With Level Vial) by Tommy Almasri

This review is for the Gem Red 82413 model.Although I needed two, I ordered one of these digital levels to check it out before ordering the second. I was pleasantly surprised with the quality of this level. I checked it for accuracy right off the bat using some known good high quality bubble levels for comparison. It passed my initial accuracy tests with flying colors.Ordering the second unit was a no-brainer.When I received the second unit I again did an accuracy test comparing the two to each other. Both units gave the same identical reading during multiple tests.Then I put the two units to work for my intended use. I'm using these levels for some engine, frame, and wheel alignment processes on my motorcycle. They performed flawlessly with dead-nuts repeatability.There are only two downsides I can even mention.First is the automatic turn-off feature. First the backlight goes out, then a minute or two later the whole unit shuts down. I wish there was a way to override this feature.The second is that when making an adjustment where the target is 90 degrees it takes some attention to know which side of 90 you are on. In my case I couldn't see the level while I was making an adjustment, so I had to make the adjustment, then go to read the level. If the reading was 89.95 degrees it's very hard to tell if you're still creeping up on 90, or if you've actually overshot 90. It's manageable, but it takes some attention and is a real opportunity for error if you don't double and triple check yourself.All-n-all though, these units are of nice quality, accuracy, and repeatability and I'd recommend them to anyone.
