Monster Digital CompactFlash 500x Memory Card 16Gb Capacity

I have read some negative reviews so I was hesitant. What I found out was to put the card in the camera and do a "Format". It works perfectly after that. Fast, easy to use. I am very pleased.

This is my first experience with Monster cards. I used it in a Nikon D300S. After three different jobs taking over 200 photos on each job, when I tried view the photos in the camera I got an error message that said there were no images on the card. However, when I put the card in the computer the photos were there. There is a compatibility issue somewhere and I am not willing to chance losing all my work in the future. Unfortunately I will not order this brand of card again. I am currently in the process of trying to return it.11/23/12 Returned this item via their packing label and Fedex. Fedex shows it was returned to them on 11/8/12 so I am not going to try to contact them to see where my replacement card is. Sad that I have to stay on top of this. I realize after so many days you can't do a new review or update your review so that's why I am putting this in now. So far not at all pleased with these folks.

Love it..works great

Used it once in my older Canon Rebel DSLR camera. After taking a bunch of pictures, plugged the camera into the computer, attempted to copy the pictures to my pictures fold and the card stopped responding. After 30 minutes of non-responsiveness, ejected the card and plugged it back in, Windows then told me the card needed to be formatted. I couldn't get any of my pictures off the camera of our family's trip.Spent about 2 hours trying to recover photos, thankfully with some free software off the internet I managed to get a few pics back. Think I'm going to go back to the old 2GB card that's almost 15 years old now that has worked without issue since I purchased it many years ago.
