35mm to 120

I was browsing through the Japan Camera Hunter shop and spotted this little device that you can attach to a roll of 35mm film to put through a medium format camera. I thought I'd buy it and give it a go just out of curiosity, and put a roll of Portra through the MamiyaRZ67. The result is a weird hybrid of 35mm and 120, but I quite like them. Even if you do only end up getting 6 shots from a 36 exposure roll.
