Digital Caliper 0-6"Measuring Tool, Micrometer Caliper with Auto-Off Feature, Interchangeable between inches and millimeters for jewelry measureme...

works good ,use it often to measure and convert measurements

You get what you pay for... but in this case. Much more. Looking for a decent, affordable tool for quick QC verification that my entire team could have. Several purchased... Consistent and so far durable. Only displays out one decimal for millimeter measurement, so not the best resolution. But again, for the average home owner (or in my case, quick QC check) they are performing well.

This is mostly all plastic, so its probably best to get something more heavy-duty if youre going to be a heavy user. Im 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 doesnt feel flimsy or like it will break easily. Has all the features I want and need. Highly accurate and responsive measurements so far. Ive noticed you can squeeze it with a little pressure when youre measuring and it might shave off a 10th of a millimeter or so, I suspect thats the plastic bending a tad, and perhaps that wouldnt happen with a high end model. For the price, this thing is great.

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.

This gadget is amazing for the money spent. I use it almost continuously to measure small parts for 3D modeling.
