This tachometer works great. This one is a lot easier to get a reading than my previous unit. Also, I like the larger screen and backlight. Beyond that, the clear hi/low limits can make it a lot easier to fine tune the exact rpm you need out of a device. One other super useful function: the auto power off can be disabled.
