Don't worry, basically no problem.

I did a lot of tests there, some of them were certified, some passed, some didn't, and they were quite reliable.

Some products have been rechecked by other testing institutions, and there is basically no problem.

If it is a jade product, you can also look at the clear picture of the real thing, which is very clear.

I hope this helps.
