My first impressions: the film is borderline awful. It's low contrast, spotty, unsaturated. Now that that's out of the way, I just feel like saying that it's awesome. I have no idea why. I took the opportunity of the cheaper color film to make my order plus a pack of PX100, and I bought an SX70 sonar (then 24 hours later my friend hands me another one, go figure.) It works well outdoors in full sunlight, as long as you shade the film well, like with a dark piece of paper. I've actually gotten differentiable colors in full sun with high development temps, though when darker it gives what may closely be described as a barely colorful images. They do have a nice quality to them.
Bottom line: film is very light sensitive, not temperature sensitive but develops well when hot (up to 100 degrees some say,) is manipulatable. It looks weird and gross but for some reason I love shooting it. It's a love/hate film but they did create a new COLOR (!) film in 18 months, so kudos to them. I've heard the new film will be legitimate, as far as I can tell this was the "we've created something, start selling it" version.
