Works ok but a bit confusing to figure out and wasn’t working on some diamonds ( real certified ones too )

If you’re after something handy to verify if your jewellery does have natural diamonds (and not something inferior) then this is great. It doesn’t come with the battery but it’s easy to set up and comes with instructions.
