this was inspired from a very old video here on YouTube where someone uses a similar invention to remedy the same issue. this video, titled "easy load fix", shows a great example of the product in use, but doesn't actually explain how it works or why it works. my video does. after I finished recording, I tested with a few cds, and found the problem was much better. it still occasionally has issues ejecting, but it's only happened a few times in between dozens of uses. this works. all materials were things you can easily find at stores in any mid sized town or city, and cost less than $20 in total. don't trust the "cleaning disks" you can buy, they won't solve this problem and can damage your cd player. do this instead
