Rock Gemstone Tumbling using a KomeStone tumbler

I wanted a rock tumbler that might cut time down a little. There were a lot of cheap one drum rotary tumblers out there but I found this KomeStone one and checked them out pretty good before deciding to try them. Support has been excellent so far and they tell you after getting your tumbler to contact them and they will send you more Rocks. Well I figured it was ploy to get you to buy but since I did I followed the info and instructions in the box when it came and they did send another pound of Rocks. Various ones but a couple were good Mohs 6-7 and two nice purple Amethyst and few agates and Amazonites. All around 6 to 6.5 -7Mohs. some other ones I am not sure of. But this is not a video review of them just what I am doing now and how it is going. I have a slower Highland Park tumbler 3lb but old one and needs some work. Sort of new at this but I studied and read books and talked with others etc before ever even starting this. I am happy I did that. Now if anyone can offer any advice or just want to comment please do I am pretty much new at this. Thank You. Peace.
