Input:
This card seemed like a good deal for the money.  It served well enough for about a month in my Nikon Coolpix digicam, but it was always a bit touchy.  The camera would do things like say "no card inserted" when coming back from a power-save "sleep" mode.  I would have to turn in it off and on to get it to work again.  It didn't lose any data, but would space out.  After a month though, it became unrecognizeable to my camera.  "Card not formatted" or something.  It still works w/ my flash readers, but not with my camera.  Dissatisfying to say the least.
