The fountain is very substantial, heavy and appears to be all stone/slate to me. not that cheap hollow stuff. It was easy to assemble without instructions. It worked well for a few months but then started leaking out the very bottom. I simply asked a question about the warranty on J&M's web site and was immediately emailed by a company representative. After emailing pictures of the leak they are sending a full replacement. So, FIVE stars to Josh and Main, As for the fountain, my rating remains to be seen. I like it and it looks and feels just as advertised. However, time will tell if it lasts.
