I was pleasantly surprised at the quality of this frame. I've heard horror stories about the Martian II frame. Missing parts, poor workmanship, holes misaligned. My frame was beautiful, all the details were there and everything was fine. The only problem was that there were no assembly instructions or diagrams in the box that came with the frame. I don't know if this is an accident or if readytosky thinks you can find out. Since this was the first frame I've ever put together, I didn't get a chance to do it without seeing someone else do it in a YouTube video. Someone who bought a Martian II with a blueprint.
