Good value for a low-cost digital caliper

While not the quality of high-end (expensive) professional calipers, this caliper is a great value for someone needing reasonably good accuracy at a low cost. The all metal construction is rugged (for a caliper) and the action is reasonably smooth. I use these calipers for wood furniture construction. The specified +/- 0.001" absolute accuracy is more than adequate for my needs, and the convenience of easily switching between metric, decimal inch, and fractional inch readings is very useful. For my woodworking applications, the fractional inch readings to 1/128" resolution, with automatic conversion at integer 1/64, 1/32, and 1/16" points, is really convenient. I have checked the absolute accuracy with precision machinist's calibration blocks, and the worst error that I measured was 0.0015", which I consider very good for my needs, but may not be good enough for someone doing tight tolerance work. I like the screw-on lid for battery that does a good job of keeping dust out of the battery compartment. The included LR44 battery (equivalent to A76 or 357A) is readily available at low cost, so battery replacement is not a problem. The plastic case is nice, but nothing special, and does an adequate job of protecting the caliper and is convenient to use. The feeler gauge set included with the 6-inch model is a nice extra, and makes the overall purchase an even better value. My only minor complaint is the decimal inch display, which uses two sizes of numerals, The two numeral sizes are OK, but the transition from large to small numerals seems odd to me. The whole integer and 1/10 inch digits are large, and the 1/100, 1/1000, and 1/1000 digits are small. For example, a reading of 1.2345 inches would show the 1 and 2 in large digits and the 3, 4,and 5 in smaller digits. I would prefer all digits except for the least significant to be large for easier reading, and only the least significant (the 5 in my example) to be small. It took me a while to get used to reading the two large plus 3 small numeral format that I feel is less intuitive (and harder to read) than a 4 large plus one small format. However, overall I was so satisfied with this caliper, that I also purchased the 8-inch version, and would recommend it to anyone wanting a low-cost, good quality, moderate accuracy, digital caliper.

Very favorably surprised!

I was very happy when I opened the box. These have a great heft to them and my initial impression was that they seem to be very well made and fairly accurate. (There is a reason we call them guestimators, LOL) Seriously, they weigh a lot (a good thing) are easy to read and very clear. They come with a spare battery, instructions, and even a micro screwdriver to take the battery cover off. Mine also came with a set of feeler gages but I haven't mic'd them yet to see how accurate they are. The one thing they came with that I wish they didn't is that chemical smell almost everything from China comes with. My suspicion is that it is the box and I am going to leave it open a few days to air out and see if the rectifies the situation.... nothing I would take a star off, but just a little gotcha. These aren't Mitotoyo's but they are 1/5th the price and for most home gamers, are a worthy addition to your tool chest.

Good so far

I just received it. Thanks to Amazon, just 1 day delivery! The caliper has all metal body. Nice feeling. The screen has a thin plastic film that was attached so well, I didn't know it was the film, and saw some scratches and even appears a broken corner. Almost return it, until I tried to peel it off and it did come off! The slider is smooth from beginning to almost near the end where it stuck. I think that's good enough for me. I probably don't use the end. So far, always return back to 0 for me when I close the jaws. The inside jaws close completely which is nice. The buttons appear to be metal. Hard and appears to be very durable. A very minor negative about this is the dial is very loose, maybe 1/32" gap or more, along the rotation axis. The case is strong, but has no padding. The case hinge is just folded plastic, prone to be broken. I will update it as I use it. But if I don't come back, assume it works good.

Know How Well Endowed You Are With Accuracy To 4 Decimal Places!

Didn't know how to calibrate it, but it came with feeler gauges with the accurate numbers printed on them. But then i saw a button on it called "zero". Very well built and solid micrometer, use it to measure my, uh, tortoise.

Great buy

Surprisingly good caliper for the price. I bought this just because I wanted a caliper that displays fractional inches for quickly choosing drill bits etc but was not expecting this to be such good quality. Appears to be just as accurate as my $95 Mitutoyo and just as solidly built, but has the plus of the fractional display.

Very accurate and reproducible

Solidly constructed. Three scales are quite usefull since some things are always measured in decimal inches and others always in fractions. The display can be used to convert between decimal to fraction by opening the caliper to, for instance, 0.750 then changing display and reading 3/4. The caliper vernier came with a set of feeler gauges, so I zeroed the display and started measuring the feeler gauges. The measurements were almost always exactly the value of the gauges, which is close enough that I often use this tool instead of a micrometer. Glad I bought it. Recommended.

Helped me out measuring for a broken watch crystal

I broke the crystal on my watch. Jeweler wanted $100 to fix it. I checked on eBay, for watch crystals, they were like $3.00 and $3.00 shipping. Glue was like $4.00. So for under $10.00 I could get the parts I needed. But I had no idea the size of my crystal in thickness and diameter. I tried using some small metal rulers I had, but I just couldn't feel confident. The crystals come in 1/2 mm steps in diameter, and thickness. I couldn't get close enough. I did think about "bracketing" my sizes, (buy sizes under/over my best guesses), but I figured that would be same cost as buying caliper. I'm glad I got the caliper. I think you know where this story is going... I fixed the watch myself, saved some money over all and now I have an awesome tool to use for other projects. When I bought the caliper, it was $20.00 and no feeler-gauge set. Total cost was about $30 to fix the watch plus a little bit of my time. Saved $70

Accurate, cheap, whats not to like.

Bought this set to replace my high dollar Mitutoyo calipers I lost in my last move. These things are great. I use them for reloading ammo. They got better after a few weeks. A little rough at first but the return to zero is excellent. I've tried to de-calibrate (if thats a word) and they stay true. Very reliable for the money.

Nice hunk of metal that feels good in hand

I pretty much find fault in everything but this caliper wipes away any petty nitpicks that I might come up with. The thing is solid, feels good in the hand and part with the LCD readout slides well (it could be a bit smoother but I'm thinking it will adapt over time). My other caliper was plastic and not only was I constantly worrying about breaking it but also the display would around so I would have to keep readjusting it. This one has a little thumb screw to lock it in place.

Well made and inexpensive

I haven’t yet made much use of this, but some things I like - large display - battery cover held with screws - it cannot fall off like some others do - the body of the slide is all metal What I don’t like - the rather flimsy case I used the case from an HB caliper that was being “decommissioned “
