Unfortunately it didn't work for me. I bought it to measure disc brake and hub runout but the dial indicator seems to have some issues. First, the zero button on the gauge requires enough pressure to make setting and resetting almost impossible, as simply touching the gauge will set the pointer in motion, thus slamming the zero down. After some practice I was able to zero it well enough by compensating with my other hand and getting it close enough to end up with a zero reading. Unfortunately, at the moment it suffers from another problem, a data leak. If I just leave it there, about every 45 seconds, it adds another 0.5 thousand inches to the measurement. Always in the same direction. At first I thought maybe it was temperature sensitive and just getting hot, but that doesn't seem to be the case as it kept doing the same thing after a while. It appeared to be more time based, although not entirely consistent. Sometimes it was about the 30s, sometimes closer to the 60s, but always around five hundred and always in the same direction. If I could zero it completely, it would go negative 0.0005 after about 20-30 seconds, 0.0001 45 seconds after that, then 0.00015 45 seconds after that, and so on. I watched it continue to climb to around 0.0005 and realized it wasn't going to stop. I've tried turning the device on and off, resetting etc many times and it just kept going. I could still get some reasonable use out of it by using it quickly and constantly checking where I had zeroed it to see how far it had risen and then simply subtracting the difference to get the actual to get the measured value. However, this is not up to the standard I was led to believe by reading other reviews. The base is fine once you get used to the way the arm flexes. It pulls well and holds up well. However, I'm not sure where the 176 pounds of magnet strength came from because I haven't observed anything close to it. He held on, but not with much holding power. Also, the power button worked to release the magnet.
