    Comments about Edu Science Know How? Ultra Quiet Rock Tumbler:

    the first thing you notice when you start to tumble the gems that come with it is that the motor is very noisey. then you find out pretty quick that if you did not get the lid on right that it leaks all over the place. the instructions arent very clear on the maintaing protion of this tumbler.
