In October of last year, I finally saw the results from the two cartridges I decided to have processed, and they were... bad. Really, really bad, as in nearly-everything-being-unusable bad. Aside from the expected issues with color accuracy, an expected consequence of not being able to scan 110 format film myself, there were serious impacts from apparent light leakage, horizontal scratching, and overall underexposure with almost all the pictures. The underexposure was due to my not bothering to take along the flash attachment at the time of shooting, but I'm not sure if the scratching came from mishandling at the lab, problems with the film cartridges, or an issue with the camera used. As for the light leakage, I don't know if this came from the camera, if there was some leakage into the unprocessed cartridges during their long residence on my bookshelf, or if something happened during developing. Fortunately, photo editing software can sometimes help salvage this kind of material.
The original, raw scan - discolored, desaturated, and afflicted with the effects of light leakage:

Not bad, if I do say so myself.
