I've been using Checkered Flag Mini since I bought my first one in 2004, ... I now also have a 2015. When I got the 2015, Frank was able to advise me on the new features and what he knew I had come to expect and love about my 2004, from a servicing standpoint. I didn't follow one suggestion and regret it, ... and maybe I should have tried that cool color combination, too... but otherwise, I was sensible and took his great advice. The 2015 had a crazy issue with a recent recall, but as usual, Frank Lindsay in service has kept me well informed and taken care of me and my mini throughout the process. I've had a Mini for 13 years and Frank has been there to assist, keep me informed, and dealt with all of my crazy issues with being a coastal ecologist taking the Mini from swamp to shore to cross-country trips (think I have the highest mileage on the 2015 so far). He has set the standard and it is a tough act to follow! Thanks, Frank!
