Useless

No instructions, doesn’t switch on, no information on if batteries need to be added and if so, where and what size, I’m totally baffled. Will be returning.

Voor edelstenen controleren is deze niet goed maar is wel een erg goede laserpen

Om edelstenen na te kijken of controleren is dit niet het goede product. Maar als laserpen werkt deze echt meer dan goed, daarvoor is deze wel een goede pen.

A ne pas acheter!

Totalement inutile!! Livré sans mode d'emploi, dans un simple petit sachet en plastique glissé à l'intérieur de l'emballage en carton Amazon. Je ne vois pas à quoi peut servir cette petite lampe bleue!
