REXBETIDigital Micrometer, Professional Inch/Metric Measuring Tools 0.00005"/0.001 mm Resolution Thickness Gauge, Protective Case with Extra Battery

Amazed that any country could make this thing for under $300! Fine finishing, great design, works exactly as advertised.Checked against another standard and it really is accurate to about .0005 inches. Holds its zero for repeated on/off cycles, even reads negative numbers if screwed down too hard. Embarrassing to buy it at this price. Nigglings: Mine does not have the data port shown in the instructions, and they do not explain what "ABS" function actually is for.

I have used this to measure my 3D prints and refine the designs. The accuracy is good for what I need it for and has a calibration cert. The display is very nice and easy to read from a distance. The controls are a breeze and easy to operate due to really good build quality. Great buy for what I need.

With a fresh battery installed, the unit zeroed easily, held its zero admirably after repeated measurements, and was easy to use. The unit produced fully repeatable measurements to the last digit on the display, which is generally a good and desirable thing for a micrometer to be capable of providing.I had purchased this item for its low price (relative to some other similar products) and because it had a bunch of positive reviews. One other convincing factor, however, was that the product listing said it would come with an extra battery. On receipt, the unit had a battery installed and it was dead. Appeared to be brand new, not a return, and there was no spare battery in the unit.So, I spent an extra $7 to get a new CR1632 3v battery from my grocery store. The battery size is somewhat unusual, so I feel I got lucky to find one locally. Amazon sells multi-packs of these batteries for just a few dollars. Unless you are doing a lot of measuring, I recommend removing the battery before storage & just keep it in the provided storage case. Something to be aware of: there is a small data port on the back of the unit - this is covered by a small removable square door - the little door is easy to displace, so just be aware. If the door gets lost, it shouldn't cause problems unless metal enters the data port receptacle (looks like a mini-USB connection). I have not tried to use a data cable with this unit.All things considered, I can recommend this unit to others, with the caveat that you may need to order a spare battery at time of order, or be ready to get one on receipt.

Just got this and I love it! It also past inspection at the CNC shop I work at!

Perfect for measuring my shims.

Testing with gauge blocks, it's right on the money. I read a bunch of reviews with people complaining that it won't return to zero... When I got mine, the Absolute mode did have the problem where it was WAY off zero, but like the Incremental mode, there is a way to reset that. It's just a different process that I figured out in about 30 seconds without even looking at the manual (press and hold the middle button.) Part of the responsibility you have when writing a review is to educate yourself on the product you are reviewing so you don't inadvertently mislead people.This is perfect for a home-owner / hobbyist on a budget. If you are a business doing high precision machining, yeah, go for the Starrett or Mitutoyo instead. My old mic is a manual Mitutoyo, but I wanted something I could leave out on the bench ready to go for quick checks and the ability to read in both standard and metric is super handy at a fraction of the price of high-end brands.

Well built. Measuring a 1-2-3 block with Mitutoyo calipers and this both reported 1.00000. I'm happy.

This micrometer worked great for a while, I actually didn't have to put in the spare battery it came with up until about 6 months ago. Just recently I tried to use it, it wouldn't turn on. I figured the spare battery was already dead, so I put in a fresh CR1632. The micrometer display flashes 'on' on the screen, and then nothing. Won't power up. Tried another fresh battery. Did the same thing. This micrometer saw very light use, and was stored in a drawer in my house, inside its case.
