The item arrived early and was as ordered I was pleased with the whole matter

Als wir das Gerät ausprobiert haben, mussten wir leider feststellen, dass die Lupe ihren Zweck nicht erfüllt. Der Gerät selbst ist in Ordnung. Wir wollten diesen Produkt zurück geben, nun leider wurde uns gesagt, dass wir den Rückversand erstmal selber übernehmen müssen. Die Sendung kam aus USA und den Rückversand hätte uns noch 50€ gekostet, von daher haben wir diesen Artikel behalten. Ich wollte den Verkäufer gerne kontaktieren, aber dies ist auch nicht möglich.....

Although the stone tester does not differentiate between actual diamonds and high quality CZ, they both pass as real, I still like it and find it useful for what I need. The kit includes a small magnifier with lights, which takes the place of a jewelers loop I guess. Again it does what I need it to do. I’ve had it for a week so far and have found many silver pieces of jewelry and a few 14 k. As for the stones in my jewelry only one doesn’t rate on the tester. I haven’t had the chance to try it on any greens yet.
