Neoteck Bore Gage Set Digital Indicator Dial Bore Gauge (2"-6"/0.0005") with Self-Centering Dial, Carbide Anvils, Insulated Grips for Deep Engine Cylinder Measurement-Black

ok

First thing to note, this device does not give a readout of the exact dimension being measured. It is a comparator that requires the use of another suitably accurate measuring instrument to calibrate a zero reading for the required dimension, then displays a numerical deviation from that setting. This isn't all that clear in the product details. Secondly, the range of the telescopic component in the handle is only 2mm. You'll need to add one or more set pieces to get the tool in the required size range. This is not a massive problem, but it does result in a lot of small extension pieces. The digital indicator itself is a generic sized unit with 12mm range of travel and would be useful elsewhere if disassembly from the plastic protective housing part of the stem was less of a faff. As noted by others, the case is rather inadequate to securely store all the many set pieces. When I opened the box they were all jumbled up, not safely nested in their respective slots. At least the small washer-like set pieces were inside a plastic bag, otherwise they would be easy to lose. I wonder why given the 2mm range of measurement we even need the 0.5 and 2mm pieces. On the subject of the case, this instrument doesn't fit in the case unless you separate the indicator from the stem. In the photos I've attempted to show that either the measuring head OR the indicator will nest into the box, but not both at the same time. The value isn't so bad considering how much a more professional instrument to cover the same range of sizes would cost. This is OK for occasional DIY use but it would drive me nuts if I was using it every day.

Could have been a faulty unit but this one didn’t measure the full 2mmm range and so there are deadbands in its measuring range that make it inefficient and not for to use

Works OK but needed better resolution, recommend using an analogue version.

Work well as described
