Description: Digital calipers are an absolute essential. Here at SparkFun we use them all the time. These premium calipers come with an extra battery and auto shut-off. Measurements can be taken in either metric or standard. The calipers are 6" in length and make a great addition to any tool set.

For the money it’s pretty good and repeatability was better than I expected. But that’s about the only good thing I can say about them. The slide action is incredibly rough and makes a horrible grinding noise that makes you wish you feel like you’re getting a root canal.
At first I thought maybe I was just unlucky but then I came across this: https://www.youtube.com/watch?v=WvszAb0Y0Ec
If you really need calipers, get these, they’re more accurate than using a potato, but if you just want a pair, save up for a better set.
Sorry to hear that your unit was so rough. I keep a pair on my desk that I have used for many years. Contact us if you would like to try to swap them out. https://www.sparkfun.com/returns
As a little background I’m used to measuring things with Mitutoyo Calipers at work ($200+). The first thing I noticed is that this Calipers don’t run as smoothly. I fixed that by adding some oil to the back rail and they still don’t run as smooth but way better than before. Accuracy is pretty good, I actually expected less. The only defect I’ve found so far is that there is some kind of problem with the auto-shut down feature so I have already replaced the first battery with no more than 50 uses. I found a post somewhere on the web where they suggested to add an external switch, maybe I’ll try it in the near future. Anyways, for the price this Calipers run they are a great deal if you are not looking for ±0.01mm accuracy or more!
I just got a 3d printer and got these to measure parts. They work as expected. No problems using them.
