My 7-year old son had it running step 1 within 10 minutes.
Easy to get started and looking forward to the results after 30 days following the 4-step process. Came with a non-UK plug which was a surprise after reading it came with a 3-pin plug. No instructions provided on what speed to run.

E davvero bello vedere i bambini quanta passione dedicano a questo attrezzo. La sua collocazione non può avvenire in casa in quanto un po' di rumore lo fa e andando di continuo anche per 7 GG di continuo non è il massimo. Lo consiglio a tutti i giovani esploratori che vogliono trasformare il grezzo in gioielli.

Bought a cheaper version of this, and it broke a drive belt almost daily. Sent it back for a refund and bought this one. This is much better, and has been running for a couple of weeks now with no issues. It is also considerably quieter than the other one (although I still wouldn't want it in a room I spend a lot of time in). Feels good quality, it's been running well and it is really simple and easy to use. Very impressed.

Es muy práctico, de momento lo estoy usando en la primera fase con grano grueso y varias piedras necesitan más días, lleva como una semana en esta fase más o menos, y le he puesto más tiempo, el tambor es muy sencillo de abrir, como precaución uso guantes y mascarilla al sacar las piedras y lo hago en un lugar ventilado, hay muchas muestras lo que algunas son muy pequeñas y amatista, solo hay una y es pequeña, me hubiera gustado que llevara 2 o 3, el grano bien, aunque hay poca cantidad y solo me da para un uso, el tambor no hace mucho ruido, tuve que comprarle un adaptador al enchufe pues no venía incluido y no ponía nada en las instrucciones, antes de comprar el producto, pero lo compré en un bazar chino, en general el kit va bastante bien y da buenos resultados por ahora, pues me faltan las otras fases, bastante satisfecha.
