Existing product improvements

I’ve been a big fan of everything Anker but i recently bought the CD slot magnetic phone holder. The design of the cd slot insert is awesome since it doesn’t have a screw that can be over tightened and break over time. My only complaint is the magnet strength and small distribution of magnetic surface of the holder. I already have one by another brand, that uses the same type of metal plate on the phone, that works great. When i placed it on this holder, it didn’t hold up as well. I still want to use just the cd slot and just replace the magnetic head. What other improvements of your favorite products can you think of?
