this is a nice to have product. it tags all my photos, even when i use the photo blast and it will then tag all 6 photos after they are completed. very simple to use. would get 5 stars if it was better integrated into the camera function. though i may have it set up to auto-start, i always have to go to the product, make sure its on, wait for it to catch a signal, then go back to my camera to be sure they get tagged.
