Actually, I gave these 3 stars only because I can't use them. I wasn't savvy enough to know that there is more than one size that you should look for in a memory stick, unless you buy a multiple card reader. I mistakenly bought something that would not fit my SanDisk...which is not HD so it was too big for the memory stick. They were such a great buy that it would cost more to send them back than they cost, so I will give them to someone with a more modern camera! Just make sure you have a memory card that is smaller than a regular SanDisk, look for Micro on your card. I wish there had been a review to tell me this.
