Worked for me without any problem

Recently, some jpg and mpg files were deleted from a memory stick. I was able to recover them without any problem. It was a very simple process. Didn't alter the contents on the card at all.

Also, a while back I used it to recover images from an sd card. I was surprised at what images were recovered. Images that were considerably old, and I hadn't used in months were still recovered.

I didn't read any readme files or instruction manuals. There was nothing to figure out: very straight-forward.

Most recently it seemed to hang after all the files were recovered, and it began an optional renaming process of the files. But the files had already been recovered, and I kept the assigned names. For me that doesn't negate the value of the product.

I have never used the product to recover files from an actual hard disk, or to recover nikon raw format images.
