This Gloss Meter comes with a test report from a professional testing agency, which tests and records its measurement performance and error values ​​in detail. I simply used it a few times and the results seemed reliable. It is very rare to buy such a professional meter whose performance is completely transparent to the user.

This gloss meter allows the detailer to quantify the amount of improvement made through paint correction stages. It also helps a detailer determine the quickest pad/polish combination to get the best results in the shortest amount of time.

This is a high quality optical tool that will be very useful to those trying to match paints with samples, especially indoors. Combining this tool with an RGB or CMYK measurement tool covers all bases. While the tool is impressive, the instructions and minimalistic and much trial and error is required to get the full use of this tool. I was also not impressed with the repeatability of readings.

This gloss meter works great. I used it for testing how even my spray pattern was when I painted my guitar. I like that you can plot the difference between the surface and minimize the difference. It really improves the way you will paint, you find out where you miss every time. It also makes me feel better about selling a finished product if i check it with the meter just to be sure someone wont see any imperfections. It doesnt come with a case but the sensor has a cover. Its very easy to use, almost doesn't need instructions, just the few combos that you need to know to be able to do everything. But if you dont read instructions, its pretty simple and easy to figure out. Im pretty impressed with it. I use it along with my paint thickness meter. That way you can insure professional results as long as it looks good before you test it. It wont get rid of orange peel for you, but vut it comes up as a different gloss rating, so you can identify spots that need to be fixed.

Whether you're detailing cars, laying down paint, or even finishing furniture... This helps you put an actual number on your finish. For paint restoration or polishing, doing a before and after reading lets you show customers that there was a measurable improvement. Or, if you're laying things down you can check part to part to make sure you're hitting within a certain percentage.I've got a bit of an oddball use of this... I'll be testing different finishing schedules on some pens I make. Rather than just saying "this one looks better" I can put a number to it and be a bit more scientific. Great way to nail down a finishing schedule and see if you can skip grits, etc without sacrificing the final product.Instructions are pretty straight forward... There's not much to the basic use of this one. Calibration is built into the cover for the sensor, don't skip that step... but... before you try that, you'll need to make sure you peel the thin plastic protection off the sensor. (Yea.. I forgot to do that...)

I work in the automotive refinishing industry and this is the type of meter that allows me to take a quick measurement of the GU (Gloss Unit) value of a clearcoat finish. The tool itself charges with a ubiquitous USB-C cable, so that's more convenient than having to use batteries that corrode. The lens cover contains the calibration tile and reference value, so you don't have a separate tile box to worry about losing. The original box comes with a factory calibration document, so that's also a plus. My unit came defaulted to the Chinese language, which is understandable, but it took me a bit to figure out how to change it to English. I'm not deducting a star for this, but do suggest that the manufacturer include a "Quick Start-Up" page in the box to get the consumer up and running quicker. First impressions mean everything to me, and this one wasn't as user-friendly as I had hoped it would be. Nonetheless, the unit works very well on flat surfaces and generates repeatable values within a tolerance of 0.1 Gloss Units. This is an invaluable tool for anyone in the coatings trade. Highly recommended, especially for Amazon's low listed selling price.

Not being overly familiar with this type of meter, had one of my employees who is in charge of our new floor division handle this testing. He compared results to a much more pricey meter and found the accuracy nearly identical. You can also grab a comprehensive report via software and third party sources. Great price and highly recommended if you need this.

So far everything seems to work and give reliable answers. The machine is easy to use and really compact. You can easily take this with you or find a storage place for it. It charges fast and actually comes with a brick and charging cord. The only slight issue is the instructions could be better. I was able to figure everything out but it could have been a bit more detailed.
