I've read alot of posts about the round stone with handles breaking. I myself have had several customers complaining. The last post I read was April, 2009. Is there still a problem with them? Last night at a party a very good customer and friend asked how customers are liking the new stones (he has many of the flat ones), since he wants to get a few for friends. I needed to be honest and told him that there had been reports of problems in the past. Well, it turned out that all he wanted was the stones so he didn't place an order and is waiting awhile to see if the problems are ironed out. I'm just wondering if I should contact him in the near future and tell him I haven't seen any negative reports since April. He knows all about the guarantee, but that I know that wouldn't be a selling point. Any thoughts?
