Bought some dough trays last year never had a problem. Bought more dough trays this year and they're completely inferior! The material is bent out of shape they're not as sturdy they don't stack up together. My dough has dried out and merged together due to how warped the bottom of the trays are. We sent multiple videos and pictures to demonstrate, we even placed a marble in the new trays to show how uneven they are compared to our older trays. All they did was fob us off with the same email saying they don't see a problem with the product and if we would like to return 3 out of 4 of them because we have used one then we can do so at our own cost and an additional 25% fee deducted from the refund! It's absolutely disgraceful they have no shame what so ever and don't even offer a reasonable alternative! We're now such with a stack of dodgy dough trays that cost us twice as much as the first ones we ordered. Stay away! Absolutely disgraceful customer service and terrible products, we will not be using this company again and I will urge anyone else to stay away too!
