Bought double barrel rock tumbler, it was the worst experience ever, faulty product (spinner stopped working the third day and motor was making a very loud noise) besides the worst CS ever. It's terrible dealing with CS, I bought through Amazon and company said they'll replace to not return. They waited 3 weeks to send and this was after a lot of back and forth emails, my 30 days period with Amazon has gone to get full refund. After 3 days after Amazon timeline was gone they send another faulty product and when returning they said but we won't return you for the rocks and the grit does are not the problem when the CS lady clearly stated everything must be returned for refund. Anyhow, don't buy from this company is the worst experience ever and very difficult to get your money back. CS has no customer service they treat you the worst.
