Volevo qualcosa per lucidare le piccole pietre che raccolgo al mare e questo buratto lo fa ad un prezzo accessibile.

Bought this for my son. Machine has been powered on and turning nonstop for the last five weeks. Results are (apart from the annoying sound and a probably exploded electricity bill) abysmal. No shine whatsoever. Stones have only become much much smaller than they were. What an absolute rip-off. Cannot understand why National Geographic would attach its name to such an inferior and non-sustainable product. This is the first review i have ever written in my lige. Please, i case you are thinking about purchasing this machine: do not buy this.

Très bien pour la verre.

Todo un descubrimiento para mi hijo de 10 años, un fan de los minerales. Solo tengo una pregunta: dónde se puede conseguir más gravilla de los distintos tamaños que vienen en los sobres?
