Digital Caliper Measuring Tool, IP54 Waterproof Electronic Micrometer Caliper, Stainlee Steel Vernier Caliper with Large LCD Screen, Inch Metric Fraction Conversion, 6 Inch for Household/DIY

I have owned “old school” dial calipers for probably 40 years. After buying and using these new digital calipers, all I can say is I should have bought them a long time ago. Great value for the money. Build quality of the calipers themselves is great and same for the case.The ability to switch between metric, fractional and inch measurements on the fly is a game changer. The LCD display is large and very easy to read.I do not use calipers on a regular basis but I do recommend this product.

I’m truly impressed with this collection of high-quality tools. The Nefish 4-Inch Heavy Duty Casters Set delivers outstanding durability and smooth mobility, supporting up to 7000 lbs with corrosion-resistant nylon wheels and reliable brakes—perfect for industrial and heavy equipment use. The Digital Caliper Measuring Tool is a must-have for precision, featuring a large LCD screen with easy switching between inches, millimeters, and fractions, crafted from sturdy stainless steel for accurate DIY and household projects.

I purchased the IP54 version (has weather sealing), as I plan on having this last and pricewise wasn't all that much different than normal. I also wanted a metal version, plastic has some give and take and I've seen a broken plastic one in the office (perhaps dropped or twisted).The stainless IP54 version comes with the unit with weather sealing, the large display, a case, 3 batteries (1 inside + 2 extra), and manual. I did not need to read the manual, the buttons are pretty intuitive (mm/in/frac, set to 0, and on/off). It turns on automatically when you use it, which is nice.The arms are spot on parallel with each other, which means when you close it you don't see an air gap at the tip or base so you can measure something anywhere along the entire length and not worry that measuring something at the base will be a different measurement than at the tip. It's also sturdy, if you pinch the arms on something and then crank down the difference is typically 0.01mm between cranking down vs firm.Accuracy is also spot on as I compare it to things I know exactly the size. The display is easy to read. I'm glad it comes with a case, though it is the 1 piece kind of case that depends on shaped plastic snaps with thinned plastic as the hinge. If abused slightly, it's the kind the snap will wear and no longer hold OR the thin plastic for the hinge will tear. Basically, when opening/closing the case it's the kind you have to be very, very delicate or it will no longer snap or the snap will tear off. I just wish I could set the fractions, as I only need to deal with 16ths this is accurate to 128. So, if looking for 3/8 it will show 45/128 then 23/64, etc. but great product.

Not bad product, only lasted 15 months before the on off switch broke. Took it apart to try and fix it, but it's a micro switch. No fixing that, would need to replace the switch and not worth it. Good thing it has an auto off, so still going strong with the original battery.

This review is for the 6" or 150mm size of these calipers.I would recommend this digital caliper if you need to measure inside, outside or depth up to 150mm.1. It comes on when you move it and does not seem to need to be zeroed.2. It comes with batteries in it and extras. I only use it occasionally, mostly to measure items I want to engrave so that I can accurately size traces or tool path limits.3. It is accurate to my ability to verify. I have some metric steel rulers that seem very accurate. When I extend the caliper to 150mm and compare it to the steel rule, it is right on the ruled mark.4. It handles well. The thumb roller that allows you to make fine adjustments handles well, as does the twist locks.Like most digital devices, you can set the caliper at a distance, zero it there, measure something else and it will give you a difference, in case you never learned to subtract. This requires that you close the calipers and zero them to be sure of accuracy.The fractional inch mode is of little use. It reads the fractions in 128ths, and cannot be instructed to round to, say, 32nds. I have little intuitive feel for, for example, what 57/128ths" is, except it is more than a quarter, less than a half. 11.78 mm or 0.448": either of those will give me a better feel for the measurement. Since 63/128" is close to 1/2" and it never seems that you hit that easy fraction when you measure, in my experience I'm going to find that the fractional inch mode is just confusing. It is just an extra button push to skip it.Compared to the quality/cost ratio, the fact that they do all the other stuff they say, well, these are still a 5 star buy for me. The only thing I might go for is bigger numbers or a connected app.The cheap blown plastic case has been snapped open and closed 100 times ans shows no sign of failure. There is no extra room in the case.

Takes accurate measurements, and it feels very quality/sturdy. Glad I purchased this.

Works as advertised.

I just got the calipers with the extra large screen .And I gotta say they sure seem of good quality so far I have not put them thru a whole lot so far but they seem to be holding a zero very well and are very accurate. If so.ething changes with more use i will do an update. But as for now they have earned their 5 stars. I paid over 4 times as much for a good high end pair and these work just as well. Not to mention this set can do fractions also my name brand ones do not have that option.
