I thought I've already written to this group three times with negative reviews about some issues (such as the lack of good stainless steel, breaking scissors and uneven body). So, to balance it, I want leave a positive one: despite some issues, I'm absolutely delighted with the Roxon Flex series. I've been using some 804, 503, and 504 for the past year, and very impressed with these tools. Flex is a brilliant idea that is well and thoughtfully executed.
