cadeau de noel pour mes parents qui aime faire des bijoux fantaisies. il me dise que le procédé est long mais que le résultat est bon. les pierres qu'ils ont ramassé eux même on perdu 50% de leur taille.

It is incredibly loud. There is no place in my house that I can run this overnight. I live in Canada, cannot leave water in unheated shed. There is enough abrasive material for one tumbling cycle. The cycles take 3 - 6 days each. Many of the included rocks are so small, they are unusable after the 2nd or 3rd cycle. This product could be better. It does exactly as intended. My son is more knowledgable since we purchased this product.

Bought this for a Christmas gift and my daughter didn’t use it until 4 moths after we gave it to her (busy school) and she used it for couple months and now it just flashes the lights and won’t turn. It’s burnt out or something. Sad, it was a gift. Unfortunately resellers don’t provide warranty so, worked for a few months, we are out the money. It wasn’t cheap.
