Grandson is enjoying working with his rock tumbler and his extended Rick collection! Polished rocks very nicely and gets good results. Takes time but does a nice job!

Very good value My grandson's really liked it we had a lot of fun and still are enjoying it. The age all depends on how engaged you are with the child you should supervise him with these anyway If a 2-year-old can really enjoy it then I think most children will as well.

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.
