Since my last report about 120 film, I've developed 2 rolls of 35mm in my Lab-Box. Both went fine. The Lab-Box is still easier to load than reels in a dark bag for 35mm. I'll continue to use it for doing single rolls (I rarely have more than 1 or 2 rolls at a time).
One thing may be an issue for some people: there are places along the very edge of the film, out side of the sprocket holes and markings, that were not developed nor fixed. If you like to expose out to the edges (e.g. 135 in a medium format camera, Lomo Sprocket Rocket) then another solution may be better for you.
