Review: Breathtaking stones! Expectations blown away. - I purchased this kit for a different brand of rock tumbler and I am currently still in the tumbling process. When I opened the box I was shocked by two things. First, I received higher quality stones than expected. Even in their rough states, I could tell that they would all turn out beautiful. This kit includes the most amazing stones any hobbyist could ever want. Also, there were twice as many stones as could fit in my brand of tumbler, so I got a two-for-one bonus by accident. My expectations were exceeded. I assumed the kit would include a few small okay-looking stones and the rest would be disappointing. Not so! The manufacturers include huge, beautiful stones in this kit. I've used another kit that included really lackluster and not-so-pretty stones, but the quality of this product blew my mind. I expected half as many stones, each at half the size, and maybe altogether the stones would be pretty lame. Maybe a few would be pretty. Even though I'm far from done tumbling this kit, I can already tell that my stones will all be beautiful. This kit is the one to buy, even if your tumbler is of a different brand. That said, the other thing I noticed is that the kit does not include any instructions, which can be troublesome for those like me who purchase this kit for another brand of tumbler. Not a problem, though, as a quick Google search and my own judgement of the stones after each cycle will be sufficient to get the results I desire. It's the nature of the craft, anyway. More of an art than a science, as no two stones will ever be alike. I will definitely purchase this again! (Note: pictures included in review depict half of the stones in the kit prior to tumbling, and the other half of the stones after the first grit cycle.)
Review: Great fun and easy to use. - This was a replacement pack for additional rocks found at a gem mine. Kids loved the first rock tumbler and watching the process . The finished product was great. Would order again. Easy for kids to use.
