As much on a compact device that works perfectly, both on my SLR, this is not bad because I have to scroll permanence photos for wifi remains active. (While on the compact, if we follow the procedure, the wifi nothing left active from the moment it is connected). It was a sensible professional purchasing to save me time, in the end I'm Always On spirit to remove my card from the slot and put it in the PC! So I have a very mixed review.
