Our family enjoyed this entire process, ( truly, in these past hard months, it has been the only unity we have found, without arguing, so thank you!!) Unless we did something wrong, our stones never came out shiny.. they are still beautiful, but all are dull.I do feel we followed the instructions to the letter.Like I said either way, we love them, and it was fun!

A bit noisy but that’s expected. It was exciting for an 11 - 12 year old grandchild to use with us on his visits. Next he’s going metal detecting in the pathways where Sherman’s army marched through his family land. You take advantage of what islocally available. Fortunately he lives in a veryhistorical area. It’s great.

Got a rock tumbler for Christmas and I love it! Had to get more grit and rocks and used the same brand as the tumbler and the rocks it comes with are really pretty and they turn out so well! Comes with instructions so it’s easy to follow. This makes a great gift for rock lovers.

Den Tumbler besitze ich schon ganz lange, dieser hat sich nach den Bildern nicht groß verändert.Daher bewerte ich diesen hier zusätzlich.Er tut seinen Dienst, lässt sich easy reinigen und ist sehr robust. Der O-Ring lässt sich einfach austauschen und auch nach Jahren funktioniert alles noch super.Vor kurzem hab ich mir dann, nachdem ich den Tumbler wieder fit gemacht hatte, die Nachfüllpackung für 40€ gekauft.Was soll ich sagen? Es sind wirklich große Steine dabei! Das ist nun der erste Beutel der drei und ich kann mich nicht beschweren. Das mitgelieferte Polierkies funktioniert auch super, nur zum Schluss bekommt das Ganze noch einen Keramik Durchgang, sonst werden die Steine nicht glänzen.Das ist der einzige minus Punkt bei dem Tumbler/Nachfülle bzw. bei dem mitgelieferten Kies.Die Steine glänzen zum Schluss leider nicht ohne extra Schritt.Das Bild oben ist nach der ersten groben Politur entstanden, wenn ich daran denke, folgt ein Bild mit dem Resultat nach poliergang 5 laut Anleitung der finale Schritt.P.s. poliert am besten immer mit der längsten Zeit!Das klappt am besten!

I purchased this for a Christmas Present for one of my granddaughters. I saw cheaper ones but opted for the heavier one and am glad I did. Works just like a more expensive one I have seen. The rocks came out perfect!!! I ordered extra sand and rocks and have found that it will give her many hours of activity with this rock polisher. When she comes to visit me I plan to help her make jewelry from some of her favorite rocks.
