Electronic Digital Dial Indicator Gage Gauge Inch/Metric Conversion 0-0.5 Inch/12.7 mm 0.00005 Inch/0.001mm

Works great. I use it to level 3d printer bed not in a machine shop. Its cheap, works great. I dont have a metrology lab to run over to to check accuracy, but it seems accurate to the calipers I use at home.

Great value for the $. Very stable with repeatability. Tested under under different temperature conditions. 60 degrees, 80 degrees F has same results as 115 degrees F.Did not have battery issues over hours of use. Disappointed that thread doesn't match Starrett SAE 4-48.This unit has M2.5-0.45 threads. LR44 BatteryVery clear display. Verified accuracy multiple times.

The digital dial indicator seems to be well made and solid. I would have given it 5 stars except the accuracy was not the 0.0002" as advertised. I measured a maximum error of 0.00035". If they had advertised the error as 0.0004" I would have given it 5 stars. If you need an instrument accurate to the nearest thousandth which I do, then this is a good choice. Only time will determine how the digital dial indicator will continue giving good performance. My first impression is I recommend this device to anyone that needs an instrument to measure to the nearest thousandth.

This measures accurately for me so far and does exactly what I bought it for. Also the ON/OFF switch properly shuts off the power so the battery doesn't run down when not in use. Many of the other inexpensive (made in China) digital calipers and gauges etc. only blank the display when you turn them off but leave the electronics drawing power from the battery. This one shuts off correctly and the battery lasts a long, long time!

I had purchased this item to calibrate the CBN cutters on my surface and when I got the tool out to us it, it would not turn on, so I followed the instructions to replace the battery and when I did the little silver piece that makes contact with the battery fell out of the Digital Indicator. Can not return because it is passed the return date. To bad I really needed this tool.

Used on my ender 3 pro for bed leveling. Worked like a charm. Great buy. Easy to read dial.

I use this for obtaining correct timing of piston to ignition. So much easier to see instead of a fluttering needle at small increments
