What is Briffidi? It’s a nonsense word, pronounced similar to graffiti, that loosely represents Brian Fitzpatrick Designs. I’m a mechanical engineer and recreational tennis/pickleball player, and I had an idea for a swingweight machine that I developed into the SW1. I manufacture and ship from McKinney, Texas, USA. If you’re local, you’ll often find me at the Stonebridge Ranch Beach Club tennis courts or at the Finch Park pickleball courts. I’m somewhat active on the Talk Tennis forums as @bfroxen. To contact me, send a message to firstname.lastname@example.org.
Are you concerned about buying from a very small business? I understand. I hope to continue producing and selling the SW1, but if something changes, it will still work. The app will continue to function; it does not contact a backend server. And, if the SW1 will no longer be supported, I will publish the app source code and the hardware design.
