Review: Thanks for quick replacement of damaged item - great product to differentiate gemstones. you should have some basic knowledge to use this tester. The item arrive with the box a bit dented and the item did not work correctly. I reported it to the seller who was very communicative. A new item was shipped out immediately and works good. great seller and great communication. thank you.
Review: Busted and Disgusted - DO NOT PURCHASE!! The unit that I received was completely non functional right away, it never even calibrated correctly. And now the company will not honor even a return becaise I no longer have the box, they have ZERO CUSTOMER SERVICE and they will straight up take your money and ignore you. FOUR THUMBS DOWN 👎👎👎👎

### ⭐⭐⭐⭐⭐ Decent machine
*by N***7 on August 17, 2019*

I had a different model than this one two of them actually. They didn’t work worth a damn. This one you can at least calibrate yourself. And it’s very easy. Other machine you couldn’t calibrated couldn’t do anything. So you really couldn’t trust it. You have to watch your calibration closely though it varies from each time that you turn it on. It’s a little bit of a pain but it’s better than the other other one I had. That one you could not calibrate it all. So I’m pretty happy with this machine
