Digital Caliper 0-8" Measuring Tool with Metal Ruler, Micrometer Caliper with Auto-Off Feature, Interchangeable Between inches and millimeters for DIY/Household and 3D Printing, Black

I use these for measuring tumblers in my laser engraving business. Inexpensive and works great.

This is mostly all plastic, so it’s probably best to get something more heavy-duty if you’re going to be a heavy user. I’m only using it for some occasional 3D print modeling, so between that, the case it comes with, and careful handling I suspect this will last a long time for my use case. It doesn’t feel flimsy or like it will break easily. Has all the features I want and need. Highly accurate and responsive measurements so far. I’ve noticed you can squeeze it with a little pressure when you’re measuring and it might shave off a 10th of a millimeter or so, I suspect that’s the plastic bending a tad, and perhaps that wouldn’t happen with a high end model. For the price, this thing is great.

For the money spent, it looks to do the job. No problems so far...

Works fine for my needs. Happy with the purchase

1/64” equals 1 gauge1/64” = .015625”Measure your cigar diameter in inchesSay it equals 0.78”Divide by .01562550 ring gaugeWorks great for checkingOf course box pressed makes it more interesting to measureGreat price works very well

Good price, solid construction, and accurate measurements.

It only goes to 1 decimal point for the metric setting but that's all I need for most 3D printing designs and woodworking. If you need more accuracy than that, you'll need to spend more than $8! There is no roller but it slides with a good balance of friction. The plastic that it is made of (the entire thing) seems fairly hard. As long as you are using the calipers correctly you shouldn't have to worry about the plastic getting damaged and affecting your measurements. The only thing I miss the locking nut to keep the calipers in place. Overall, I would definitely recommend to someone on a budget or who wants a cheap second set.

Caliper; metal construction, extra batteries,Auto on feature; move the gauge and the display comes on.Solid construction. Excellent for the DIYer, Feels like a much more expensive product than it is.
