I bought the whisky flight trays from them and called for some more information so I could make my decision. Kyle was very helpful from start to finish with me. I decided that I wanted to do the three slot trays and buy four of them, he let me know they only had three of those and I would need to get a four slot tray for one of them. They were awesome and cut the cost down to accommodate me so I could get the tray for the cost of the three slot one. Overall I would highly recommend this company for their quality products and excellent customer service!!
