Excerpt: Works as advertised however in my D810 the wi-fi disconnets all too often. This is with either my iPhone or iPad. I checked the setting on the camera to make sure it was not shutting down and it's staying on.Aside from that, it's a great way to quickly see your images, have them backup in almost real time.I really wanted it to be a 5 but due to the diconnecting (and diffuculty reconnecting) a 4 is being generous.
Excerpt: The card works mostly as advertised, but unfortunately there doesn't seem to be a way to set the Android app to save to an external SD card (the option is there, but whenever you try to point it to an external destination, the app complains that the device is not writable...).
Excerpt: I did not have much experience with digital cameras since the smart phones (especially the 6) were so handy. I finally got the Leica M, Type 240 which is a great travel camera, except it does not have the wifi capability. With this Eyefi card, each picture is transferred in seconds to the iPhone and/or iPad. It is quite slick if you are not in a big hurry to transfer. The set up to connect is easy too.
Excerpt: I currently use a Canon 60D and although it doesn't have wifi capabilities, this card has been a life saver for putting out my high quality photos onto the web in a minute or less. I used a 60D, coupled with an iPhone 5 running on pre-iOS7 firmware and Eye-Fi STILL supports the outdated version of my phone. To anyone who has a DSLR, I would say the convenience of this product has been flawless for me.
