I bought this to convert 100 slides and it was worth the $40 investment. It's simple, intuitive and works. I used this with a Galaxy Note 9 but it should work with any camera phone. I didn't use the suggested app because I already have several photo apps. Because the light is projected through the film onto the camera lens, your phone may overheat. This happened to me after 30 minutes of continuous scanning. I just paused to let my phone cool down and then continued scanning.
