About three weeks ago I purchased the PVC ID cards and "M" Tray from Brainstorm, only to discover that the Tray would not operate correctly with model of printer that I purchased. I contacted Brainstorm and not only did they send me the correct Tray they did this gratis. In addition now that the Tray changed they need to redo the instruction and settings on the printer. They helped me every step of the way, even so much as to use a screen sharing app that allowed them to correct everything remotely. Not only will I buy from them again, I'll be sure to spread the word about their helpful attitude and genuine concern.
