Be careful with this tumbler
My son is very into rocks. We had a rock tumbler that was wearing out and leaked, etc so I replaced it with one that looked exactly like this. It was bought from Hobby Lobby sold under BK Scientific. My son was very excited to finish his batch of rocks that we had started with the old tumbler when we had problems with it. This tumbler ran for about 6 hours when it started having difficulty. I worked with it over a few days but could not get it to work. It takes about 3-4 weeks to finish a batch of rocks. I emailed the company as directed in the package twice. It has taken 2 months and 28 days to get a reply that told me to read the trouble shooting directions. I think that the fun potential and learning potential of this toy is great but it wouldn't work and the company didn't care.
