Guys its just a tool to do quick painless backups on the go so you can keep shooting and not whip out a laptop every time you want to review if you need to. I cant begin to say how much this type of tool is going to benefit 1 man band shoots when quick turnarounds are needed and or clients are present to make selects on the go mid shoot. Thats all this product is for. Skeleton crew easy, quick, reliable backups and viewing on the go with a few more goodies tossed in the bag. NO MORE HATE!
