I purchased 13 bags of Caribbean Rocks each one weighed 30 lbs. Most of them all cracked. They were used as a border around the edge of the lawn. No one walked on them. I could not return them because it was passed the 30 day return policy and besides that, it would not have been practical to ship 390 lbs of rocks back to them. It would have cost me more than I paid for them. They refunded me a total of $5.42. I am a senior citizen on disability & had to hire someone to do this project which only escalated the cost. I think other consumers should be made aware of the problems with this product. DO NOT BUY IT!
