  • First off, the product was as described and even better! I was assuming it would be based on reviews. But the customer service is AMAZING! Fed-Ex was not updating the tracking info, I emailed the company and they said if the tracking hadn't updated by the following day they would send another. Thankfully fed ex updated. They were going to send one out based on weird tracking info. Top notch!


  • Wow. amazing service!!!!!!!!!! I received this product and it was my fault with a bad install that I destroyed one. I emailed to see if they would sell just one and explained my poor install issue. They comped me one for free . I will certainly buy again from these folks. Little do they know I am making a bunch of boards for my friends bar. . Thank You. '!!!!!!!!!!!!!!!!!


  • These are beautiful. And they are a great size. I was worried they would be small but they are not. Nice big size. I did have to contact customer service with a question and they responded right away. They were very helpful. Great product, great customer service.
