I met Ian Gvozdek, president of Devonshire Manufacturing at their production plant last year. I was really impressed by their production process and extremely well thought out and durable designs. I have put my own copy of one of their smaller gimbal head products through hell and back on lenses/camera combos that laughingly exceed the head rating and they have worked flawlessly. They also develop other interesting photographic solutions including replacement feet for super telephoto lenses that convert them directly to a swiss arca type mount among other niche and useful products.
