The seller sent me an item different from what I ordered. Therefore, I have no comments on this item. The lesson I learned from this experience is that the seller, Blue Proton (PO Box 333, Mineola, NY 11501) is unreliable, uncooperative and seems not to give a damn to the customer. I will stay as far away as possible from this seller.Get more detail about SanDisk SDCFH-004G-A11 4GB/15MB Ultra II CF Card ( US Retail Package ).
