XH Dial Indicator with Magnetic Base Holder Fine Adjustable Long Arm 0-1" r Gage Gauge 0.001"

Purchased these for a work project and they work as designed. No issues so far.

Works exactly as intended. I'll be doing a regear in the jeep and so far I've used it to check the runout on my ring gear and so far so good. Nice tool to have and seldom use.

This is an okay kit. If you are a professional this cheap of a kit is obviously not for you. For the avg. DIYer around the house though it works good. I have used it to check run out on sprint car axels and since its not NASA I am confident in the readings. Accurate enough for what I need. The magnet is not the strongest and the adjustments are a little bit of a pain. If you need something that will "work" for cheap this is it. If you need something more accurate and professionally built this is not it.

In the process of going through all the mechanical systems on my 1979 F-150. I had the rear differential apart cleaning and inspecting it. I used this gauge to make sure back lash wasn't excessive. It confirmed I didn't need to replace ring & pinion at this time. I am sure it will come into use again when I tear into the engine down the road to refresh it and install a new cam. Regarding accuracy, this is a cheap tool and I am not expecting the same level of accuracy you would get spending a lot more for a higher end gauge. I am not engineering a bridge nor using this device every day as a professional. it is accurate enough for my needs. I would be nice if the magnet was a bit stronger though.

I guess it depends on what your trying to measure. If its run-out on arrows, or reloads, get the more expensive ones made for that. This is a little clumsy, and is hard to get a good read on.
