Review: Worth the price - Just like the description
Review: Works amazingly well if you practice - Initially I thought this multi tester was unreliable. Turns out I was the weak link. After reading other reviews and watching the product videos, I realized I wasn’t putting adequate pressure on the stone. After being mindful of the stone cleanliness, probe angle, and pressure, I’m identifying stones with precision. This is a prograde device which does require practice and patience. I’m extremely happy with the purchase.

## Questions & Answers

**Q: how do you calibrate it?**
A: Calibration is not needed as far as I know

**Q: Placing on diamonds and having no response, what does that mean?**
A: I have used this unit and had the same response on known diamonds.  Sometimes the stone is dirty and needs a cleaning.  This can throw off results.  Also, my unit is getting returned when I have a suitable replacement.  It sometimes takes 3 or more tries to get it to register.  Clean the stone and try touching it with a firm but not point grinding pressure a few times and if it doesn't work try another tester.  Assuming of course you know the diamond is real.

**Q: why one is 17.00 and other cost 265.00 same dis tester**
A: By cheap get cheap

**Q: How can I get a replacement tip?**
A: You can get it replaced from manufacturer, fill out the return form.

### ⭐⭐ No es tan confiable, muy caro para lo que es.
*by M***O on 11 February 2024*

El producyo aparenta muy buena calidad, pero no es lo que promete. Tengo casos en los que un diamante HPHT es leido como diamante cuando esta sobre la placa de aluminio suministrada y una vez montado en oro lo lee como Moissanita. Casos en los que pequeños diamantes naturales los lee como Moissanitas. Y casos en los que a las Moissanitas las lee como diamantes.. Aun limpiando, aun cambiando pilas, aun verificando angulo de toma, aun con todo lo que se recomienda hacer, lls errores de lectura son persistentes, por lo que no es confiable su uso. para eso, vale mas comprar un diamond selector de 150 pesos (conductividad termica) y un Moissanita terster de 150 pesos (conductividad electrica) y con menos del 10% de lo que vale este producto tienes los mismos o incluso mejores resultados de lectura, ya que con esos aparatos baratos si temgo lecturas persistentes de lo que se trata.
