Title: annoying
Review: The rock tumbler is very annoying.It makes a very loud sound so you have to put it in a location far away from you or you won't be able to sleep.It takes a very long time to transform the rocks into gems so it is dangerous to keep the tumbler plugged in for so long.In the end, I ended up only using it for 1 day because my parents didn't like the noise.
