The packaging of the product was flimsy, and when I received it the bottle was smashed and half of the capsules were destroyed. When I took the product I felt a lot of discomfort, which stopped as soon as I quit taking the capsules. I tried again, and the pain returned. I requested a refund, which they said they would grant once I returned the unused portion. This I did, and never saw a refund. Also, it did nothing for the kidney stone.
