0-6 Inches Digital Caliper with Large LCD Screen and Auto-Off Feature | Inch & Metric Conversion Measuring Tool, Perfect for Household/DIY Measurement

this is excellent for measuring small pieces of hardware like nots, screws, bolts. works both in metric and inches. good value

I needed calipers for 3D printing project and these worked great. If you need accurate but not perfect, these are a great choice.

I’ve been 3D printing for a few years now and this is a great tool to have. Accurate and easy to use.

I needed this for one small job and I went for the absolute cheapest I could find. It is made of plastic and I had to be careful in writing down the measurements as it easily slipped during the process. I am using this to measure a model I am scanning to make 3D prints and the measurements are close enough to work for me.

I’m not sure how perfectly accurate it is, but for my use it isn’t super important. For the price, I can’t complain. I build, rebuild etc rc cars. I use this for measuring screws, hubs, wheels, tires etc. it’s close enough to accurate to work for my need.

Excellent value for the price. They are plastic and don't last forever but if you take care of your things this should last awhile. I have bought three of these and have lost all three battery covers. The battery however does still stay put. The caliper is very accurate. Can't ask for much more for the price!

great tool and value

If you buy a 3D printer, you need this. I use mine daily to check the accuracy of prints, and to measure items I am duplicating or redesigning. Inexpensive and simple to use. It can measure regular width. Inside width and depth as well. A button switches from metricto imperial.
