The installer was very professional and answered all my questions as they were asked. I don’t have much experience with the doors, but I’ve seen them are various car meets and shows but wasn’t impressed by how hard it was to lift the kit up. The guy said the kit on his car was the Vertical Door inc brand and that he already had an appointment with you guys to take his off and put on your kit. He said you developed your own kit that addresses this common complaint. Well, I can honestly say you for sure have. having used now both of these kits i can with confidence say, I’m glad I went with yours. Thank you very much!
