I love this thing. For those looking for a great way to fix what's broken or just get more life out of your Zune, this is the thing to try. The tools are magnetic tipped and help prevent loss of the screws inside the Zune's tiny crevices. The life of this new battery is many times greater than that of the original battery, which is amazing considering the price. Given that you can re-use the tools on an I-pod or any other small electrical device, this is a steal in terms of longevity. Have a Zune that's bricked? This may be the way to save it from the trash pile.
