I bought this thinking that it would be a great way to charge my Zune away from my computer. I realize that this isn't Zune equipment, but even so I thought it would work much better than it does. It will not connect to the Zune well, and does not lock in to the player solidly. The clips are stiff and ill-fitting. You have to get it 'just so' in order for the player to charge, and if you try to move the player at all, it just falls out. Without a solid connection to the player, you can never be sure that the player is being charged properly or not. Spend the extra money and buy a Zune authorized product.
