Review on 📸 USB Powered 35mm Negative Slide Film Viewer with LED Light - Portable Handheld Scanner for Old Slides - 3X Magnification - Suitable for 2x2 Slides by Scott Chen

This is perfect for me. I have over 10,000 negatives to scan and it's a lot easier than previewing each negative with a negative scanner. I also tried it with some slides and had no problems installing or extracting them. Ignore negative reviews. They are written by people who have no idea and refuse to read the instructions. It's perfect for what it's meant to be.
