Good value. I bought 2. They are consistent with each other and tested accurate at various ranges. Each one came with one battery already installed, and a pack of 2 spares. Comments: Strangely, the battery department requires a Phillips head screw driver. It is included. Be very careful not to lose these extremely tiny screws. Hint: Before using - always push the slide closed, take your finger off the slide, and then press the ZERO button to calibrate the readout. Hint: These are made from carbon fiber infused plastic. They are very sturdy, but they can flex. When measuring, do not use too much force or you can alter the reading. Hint: When the calibers are totally closed at 0.00, note the gap at the top of the measuring faces. They touch on the lower 3/4ths of the faces. When measuring, be sure to use the lower part. If you measure in the upper gap, you'll be off by about .04". ********** Accuracy testing: There is nothing more in this review except for technical details of the accuracy tests. Don't bother reading unless you are into this sort of thing. The accuracy tests had excellent results. The precision is supposed to be .01". I found they were about 10 times that accurate at about .001. That's as far as I can test with a readout that only goes to 2 decimal places. I used a set of Grade A2 precision gauge blocks to test. They are factory certified to be within 0.0002". For the .01 resolution of these calibers, these gauge blocks are WAY overkill. But I have them sitting here, so ... See the attached photos for measurement examples. Most of the measurements photographed were taken with the blocks left in the case, so the measurement shown in the case below them match the block used On a couple, I had to reposition. On these you can see the empty slot to the right under the caliber and read the measurement there. Sorry for the focus, I was hand-holding the phone. To make the numbers show, I was also hand-holding a flashlight. Most turned out OK, but at least one turned out pretty fuzzy. All measurements were done holding them properly with any multiple block wrung together. Only the photographed ones were done a bit sloppy. Luckily, at a resolution of .01, they could be sloppy and still be accurate. Very different from my normal measuring. To test for accuracy, test what a known item measures. Then, also test to see at what point a number rounds up. Then do these tests a various places along the slide. I tested 4", 2": 1" and .05". Then I tested to see where it rounds down/up. .105 measured as .10" .106 measured as .11" So, the rounding happened at precisely halfway between .10 and ,11. Perfect. Way better than the specs. Within .001 for a stated resolution of .01. Very good. In another set of tests (not photographed), I took the 4,2, and1" blocks and tested each with the addition of the .105, .106 blocks. They all rounded at the same place.

Overall, this is a decent caliper, and gets the job done. I would advise getting a metal one, if you are deciding between a cheaper plastic one and a metal one. Its worth the few extra dollars. The plastic ones can bend, therefore not giving a perfect reading. Decent quality for the price, and with easy controls. Its very handy to have the choice to switch between centimeters and inches. Its easy to read, and gives a pretty accurate reading.

The Sangabery Digital Caliper is well-constructed using lightweight ABS plastic and features a digital measuring gauge that offers quick and accurate readouts. It supports both inch and millimeter units, allowing you to switch easily based on your measurement needs. With a measuring range of 0 to 6 inches (150mm), it’s suitable for small to medium-sized objects and offers decent precision for general-purpose tasks. While the ABS construction keeps the tool lightweight and affordable, it does make it feel somewhat fragile compared to metal alternatives. It’s perfectly suited for occasional or hobbyist use, but for frequent or heavy-duty applications, the all-metal version is a more durable choice. Overall, this is a budget-friendly and functional digital caliper that serves well for light-duty measurement needs.

Fluent movement, accurate measuring, and good enough quality come together in a tool I never thought I would own. And then I got a 3D printer. This has helped calibrate the printer as well as measure things to make on said printer and it does it job perfectly.

Easy to use. Well made. Useful and accurate

I needed a set of calipers because I am making a new saddle for my guitar. I needed to know what the width is on the old saddle. That being said, these set of calipers are not the best whatsoever, but, for a one-time use, it will get the job done. I've used expensive calipers in the past, but, I didn't need to break the bank either for what I need them for. Seems like even though they are plastic, they work well. Again, these calipers are not the best and I would not reccomend using them for everyday usage, but all in all, they're good. I will say that I was impressed how they included 2 extra batteries.

You get what you pay for. The jaws are cheap plastic (maybe a plus for you, not what I was looking for). At least the measurements seem to be accurate, plus it came with replacement batteries. Gets the job done, but not the nicest calipers I’ve ever seen.

Good price and functionality. Slides easy
