Query: It works... if you follow the instructions.

I bought a bottle of iDrops directly from the manufacturer some time ago. This small bottle with eyedropper includes enough fluid to treat at least two Macbooks or its equivalent area for iPods if used as directed. If you apply the product as per the instructions, you'll eventually remove all but the most deep scratches from your iPod. But you need three other things: Patience, persistence and lots of elbow grease. You won't see an improvement until about 15 minutes or so of constant buffing, and it will take at least 45 minutes of nonstop buffing to effectively remove scratches. And a soft, used cotton rag will take you there faster than a microfiber cloth. If you can use a rotary tool for this, I think it should work as well.As a bonus, this doesn't work only on Apple products - any item featuring an acrylic-based surface can benefit from scratch removal with iDrops. The manufacturer does not reccomend its use on LCD screens, though.
