I bought one of Stu’s first production models back in about 2016. I’ve used it extensively on my RV-7A build and It’s still going strong. I continue to be impressed by the high quality workmanship that went into this remarkable tool. You can’t go wrong with Stu’s gear - long lasting and built to the absolute highest standards. Cheers, Warbo RV-7A, VH-X7A.
