I only put a one star because I need to put something. But honestly they would get 5 stars if the rating was for the worst reviews. This last December 18, 2017, I bought my wife a set of Cabernet glasses. They were expensive glasses, but she's worth it. She loved them, thought the wine tasted better and was truly happy she has them. First week in February 2018, one of the glasses broke in the dishwasher. Right on the Riedel box it says dishwasher safe, and good for 1500 cycles. This glass was on one side of the dishwasher and nothing else near it, just to make sure nothing else would possibly brush against it, also, it was the first time through the dishwasher as I usually cleaned them by hand. I've made 3 separate attempts to contact Riedel through their website, with not one response. Now imagine my shock to go on Yelp to place a review on their "OUTSTANDING" customer service, and I read several reviews of the exact type of customer service that others have received......NONE!! This was my first and last purchase of Riedel products. My next step is to go put a bad review on the Williams Sonoma store in Rochester Hills Michigan were I made this purchase. I no longer will shop at a store that sell products by companies that wont offer any level of customer service. read more
