Very handy for those dimensions under 4". I only wish it had an auto off.

Photo is of my newest Mitutoyo 4" caliper next to my "old" 6" dial caliper--both in front of my 1934 built Gerstner machinest's chest.I purchased the 6" dial Mitutoyo caliper in 1983 in order to take a few machine shop classes at the local vocational school. I was also working with many engines and decided I just had to have a dial caliper. For almost 40 years that caliper has been my go to measuring tool in the machine shop and on an engine bench. Additionally, it has been a constant travel companion always in my briefcase and logging more than 1.5 million air miles.Recently I have been doing more work with my small machine tools (Sherline Mill, Taig Lathe, Grizzly Micro Lathe). I figured it was time to have a caliper both in the travel bag and near the machine tools.After 4 decades of use, I had no reason to select anything other than another Mitutoyo. There are lots of cheaper items (usually China sourced) and some more expensive (Starrett "real" product). But Mitutoyo still offers a quality (this one is Japan built) product at a reasonable price. Plus, I expected that the fit, feel, finish and accuracy would be on par with the 6" inch.I could not find a 4" dial and as a crusty old guy was reluctant to go digital. But, I finally decided to pull the trigger on this one.Thoughts"Unit is smooooootttttthhh. Just like it had been used for years and kept well adjusted and oil. Not loose, no burrs ro tight spots just that right feel and smoothness. If you use a measuring tool a lot, you just have the expectation of that feel to help ensure your accuracy is spot on. This on is, out of the box on par with any I have used.It is balanced better than I expected. I wanted a 4" due to the tight spaces and small stuff I encounter with my tiny machine tools. I was however, concerned that it would not "lay in the hand" like the 6". The materials and weight make that a non-issue. I was making some flats on motor armature shafts yesterday and the 4" was perfect for my feel and use.The digital calibration, brightness of LCD, ease of changing battery are all appropriate. In fact I found no dislikes in the form fit or function. I could do without the yellow stripe, but that is just an opinion rather than a function item.Accuracy was spot on as I measured a few test blocks. Comparing measurements of my armatures with both indicators yielded less than .001" difference.The readout was instantaneous and stable. I was a bit surprised at how quickly I adjusted to just reading rather than counting on the dial.In short I am pleased with the purchase. I was prepared to not like the length (balance) and feel and be aggravated by the digital readout. In turn, those are the best part of the unit. Now if the digital holds up like the dial, I (or my heirs) will be using this 50 years from now. Great feathers---great feel---perfect for application---long life. Those are the reasons a pro buys quality.A note on the photo. I purchased the Gerstner chest at an auction. A small rock quarry was being sold after the owner's death. His machine shop was amazing. All line-shaft driven tools in well used, but immaculate condition. Saddly, most were bought by scrappers. I bought the chest that still had a few tools in it. A few years later, I had Gerstner do new felt, chrome work and leatherette at their plant in Dayton, O. I left the wood as is. They dated it (numbers and marks on drawer bottoms) as 1934 production. Proud to say it has been used as a working chest ever since..first with the rock quarry and then with me. Not many years until it will have been in use 100 years, further proof that quality tools well used will pay. Knowing this chest now holds a "state of the art" digital caliper as it nears 100 years of service makes me feel more of a "steward" rather than "owner". Perhaps not part of the review, this does reflect my view of a life-time of working to build and use skills while appreciated what good tools can me.

You get exactly what yo pay for here. Accurate durable and high quality
