I have had a roll of Rollei 25 RPX in the Olympus Trip 35 for over a year. Finally finished it up. At iso 25, this film requires bright light along with a steady hand. A lot of the time I had neither. Out of a roll of 36, maybe 5-7 are any good. I think this one is one of my favorites – it has people in it! Most of my pictures do not – so this is a rare occasion on this end!
