Highly recommend this product very easy to use. Instructions were easy to understand. Great value for the price durability is good. Packaging is good. The accuracy on this product was good as well. I would recommend this to anyone that is wanting to check any type of jewelry diamonds, etc. great product. For the money.

arrived on time and works great

I found all of the pieces worked as stated. I was particularly impressed with the portable microscope. I can actually read certification numbers on the girdles of the diamonds. Amazing! The diamond tester seemed like the first ones that came out many years ago. I tested with known samples before I rested results on it. Then along came a Moissanite. A moissanite tests as a real diamond. I cannot figure out why. They are made from different materials. I tried warming the stone first. No different. So if you use it rule out moissanite.

Good product for the price. It has to warm up to get an accurate reading. It helped me determine if a ring was fake which I returned. This product will save you money. It saved me hundreds.

Not sure I can depend on this. But may be it's user error?

Defective product, and the scale doesn't work.

It arrived in perfect shape and it works fine. Still playing with it.

I replaced my tester an scale after loose the original to hurricane damage

Good product All elements are working properly

A bit too expensive

I was confused because this is meant to be a diamond tester but I placed it on metal by accident and it hit the top telling me that the metal was a diamond crazy right😵‍💫

le détecteur et la balance sont tres biens,c'est la loupe qui laisse a désirer.Suis contente quand meme de mon achat.

The unit works, but testing a diamond, zirconia is all shown as a positive diamond. So, it works, but not correctly.
