INSIZE 1108-150 Electronic Caliper, 0" - 6"

Very nice calipers, smooth action, decent priced, accurate and so far goes back to all zeros everytime the jaws are closed... and it has the 3 volt 2032 battery, not those tiny 1.5 volt button batteries that don't last long.I can't say anything bad about these really, except if given a choice I'd rather it had fractions along with inches and mm. There's always a conversion calculator online I can use if need be, so no big loss. I can't say I actually like the color of it, green isn't exactly my choice there either, but heay, for the price and quality I can deal with that also, won't stop my 5 star review. I would recommend this brand and not just because of said things listed, but also because they've been tested and quality assured with a certificate claiming it. How many calibers you can buy actually do that?... I bet not very many. These have a actual serial number, no one does that for a tool they won't guarantee, it's proprietary for each caliper.Update: still keeping my 5 star review however, the calipers don't like to zero out by themselves once the battery is pulled and put back in, but once it's reset to zero the first time all is good. I took the thinnest item I could find to test these calipers... a cat hair. No the cat didn't mind it and no harm done, hairs fall right off. Anyways, when I measured the hairs thickness it measured the same everytime I measured it, it never varied... now that's precise.

Put up all of my curtains with ease. Measuring from the side of the trim and the top of the trim repeatedly, quickly and accurately helped me mark my spots to drill for 4 sets of curtains making the job easy and under an hour.

Nice ergonomic design with great battery life. After 2+ years of daily shop floor production use, the Inside digital 6" caliper is performing flawlessly. The instrument is calibration tested every 3 months and hasn't missed a beat as of yet. Good value for the money. Actually costs less to replace than to refurbish.

According to Amazon I purchased these April of 2021. Sounds about right. So here it is July 2023 and they've been getting daily use in a machine shop for a little over 2 years. They're still pretty much good as new. I've had no issues with accuracy, and I've only changed the battery one time, although it probably is getting about due because it's been close to a year. I just got a 0-8 set in last night and that did remind me that I was not super happy with them out of the box, they felt a little tight and not as smooth as Mitutoyos. That cleared up on its own fairly quickly with use though and it didn't take long for them to be as smooth as the bigger name calipers. For the money, you can't beat these things.

Inexpensive set of calipers, needed a backup pair, and these will do fine

I've had more calipers than I should have needed to buy in my time. Problems I've had are with the zero. With the calipers I bought, going back to zero never got fully zeroed out. This Insize caliper does (it's not perfect but almost). The battery in other models was that tiny one and the compartment it was in had screws that stripped out so that the cover wouldn't shut. The Insize uses the CR2032 battery, the larger one that lasts longer. I like that. And the cover to the battery slides out with a thumb press. Mush better than having to unscrew tiny screws that strip out making the caliper useless. I don't know how durable the Insize caliper is is yet. That is the next test.

Excellent accuracy as shown by repeatable measurement and by comparison with micrometer. Convenient automatic turn on when moved. Holds its position firmly, but moves easily when you want to move it. I love this calipers.

What do I like: the quality, the price, the repeatability. I have one of these and an 8” at each machine in my shop. 7 total. Very good, I hope the price stays the same. It has already inched up a little. These Chinese guys know what they are doing. Thanks for asking.
