Very convenient
Everything is included except the rocks, tumbling compound an water. Good clear instruction. You may want to experiment with the length of tumbling with each grit you use based on the subject you are polishing. Good, clear instructions.

Good product
Good grit to start off rock tumbling. Only con is that there is one scooper so you would need to buy extra scoopers
