I've seen the loader, and almost invested in one. On further research it seemed like more trouble than it was worth. I suppose that if you had an open space to load the reels, then it wouldn't be to bad. How ever, I doubt that you could use it in a changing bag. Like they say about getting to Carnagie Hall, Practice. Stainless reels can be a bit dodgy to load, but if you take a scrap roll of film, ( be sure that it is the same as you shoot) and just sit down and practice loading in the light. Then do it with your eyes closed, then in the dark, or in the changing bag. Eventually, you'll get the feel of it. I will admit howeever that after many thousands of rolls of 35, and 120 film, I still manage to run into a problem roll from time to time. I acually had more trouble loading the old Yankee plastic reels.
