Wonderful Tester
I owned one of these testers for many years before it just stopped working recently. So i decided to buy the same brand and thus far it has not disappointed at all. The green LED light and beep when a diamond is tested is particularly useful for my customers to see that Original Diamonds are set on the item and not Simulants. The actual testing tip is extremely fine and have been used to test even one point diamonds (ie .001). It came also with a very nice storage pouch with a little slot inside to store the batteries when not in use. This model requires 3 AAA batteries. It does not come with rechargeable batteries. I'm hoping this one lasts just as long as the previous one. I would most definitely recommend this tester to anyone in the jewelery trade.

No instructions or box, came in padded envelope.
I have used one before of same durability, it works easily. However no instructions or not box was included it was shipped in a padded envelope. That would’ve been nice to have, unsure if was brand new or not. The items works for what I needed.

Wow. I should've read the reviews before buying this ...
Wow. I should've read the reviews before buying this. If I had known that it didn't have an adapter before paying this much, I wouldn't have bought it. How would I go about getting an adapter for it?
