Great for sort out fake gem stones

Reliability is hit and miss.
Looks good and sounds like it would be a good investment for gem testing, but in reality it is not very reliable. You can test the same item multiple times and get different results after each test. Not really worth what they charge, and I probably wouldn't recommend this product....

Faulty and UNRELIABLE From The Start.
This is my 2nd unit. My firsttester worked great for about 4 years. This new unithas been anything but usable. Stsrts testing without touching a stone. Gives false readings. I wanted to send it back, unfortunately, I didn't use for the first two and after giving it some testing time, it was past the 30 day return period. Very frustrating and I lost $$$.

Works but should have bought a different one
It’s a little vague when narrowing down gems. Battery life isn’t very good spend a little for and get the analog model.
