Have used this for a couple years now and it's only gotten better and better. There is so few good recovery programs for Macs out there I've even sent letters to the developer to please continue to develop it because it really does work well. I do mac repair and IT consulting for a large, name brand company with a Yellow background (hint)... and we use this software many times over the software than what we are provided by corporate. This just works. The RAID recovery is the only product of it's kind, and the photo recovery is SO MUCH EASIER than looking through 1000s of files for the right one... it's ridiculously easier. Our customer's are happier as a result.
