Works great! So happy to have the extra bit of storage space.  I wasn't really sure how much use I would get out of this, so I just got the 4 GB card.  For the price, if I really need more space, I could just get a bigger one and use this for something else.  But, so far, it's been plenty of space for me.  I'm not storing a lot on my phone, so I don't think I'll need to upgrade.
