Pros: It's not a slow card. It DOES work to send data wirelessly to my phone. It's still working

Cons: Unfortunately, the app has no way of "pushing" the data when you want it to. It will send everything on the card, seemingly whenever it feels like it. If I'm out in the field far away from any other Wi-Fi networks the card still takes a while to connect and if you're really just after that one shot, you've got some waiting to do if you've been shooting several prior. It hasn't damaged any of my photos or lost data for me in any way, but the back plastic dividers on the pins break off the card very easily. The first SD card I've ever had that happen with. Since this card is so intermittent on deciding it wants to transmit data to your mobile device, you end up trying to keep your camera on for a few extra minutes. It's quick to drain your camera and phone batteries when these moments occur.

Other Thoughts: The Eye-Fi Mobi is my first experience with Eye-Fi cards in general and I figured I'd wait a couple of months before writing the review...I still think this IS a solution to a problem with cameras that don't support wireless. If you need it, this will work. It's just not that great and the app is kind of clumsy.

Pros: Still the same as in my last review.

Cons: Still the same as last time but got one revision:

Other Thoughts: One thing I mentioned before is that I might have to make my iPad forget the usual wifi connection so it would always default to the Eye-fi card, but it won't work that way either because the Eye-fi card creates a network only when it needs to transfer pictures, otherwise, it stops broadcasting. On my iPad, the shortest way to reconnect to the Eye-fi card once it tries to send pictures, is to pull up the Control Center on the iPad, turn off the wifi, wait a couple seconds and turn it on again. As long as you have your regular wifi connection forgotten, it will reconnect to the Eye-fi card.

It must be much better on an iPad or device that has cell network connection because it could stay connected to the Eye-fi card and upload to the Eye-fi Cloud at the same time, although it might still have issues reconnecting to the card after a bit of inactivity.

Pros: More convenient than having to pull out the SD card from your camera, and then needing an SD to lighting adapter on my iPad Air. This means wirelessly view and store pictures taken with your camera on your iPhone/iPad/Android faster than any wired connection would allow you to do the same. It has some storage so you got a buffer of, in this case, 8GB before you are forced to transfer those images elsewhere.

Cons: Doesn't work for transferring files from the camera to a desktop computer, for that you'd need the Pro X2, but I think this card should have been made that way from the start.

Ok, that's was almost nitpicking, but the more serious issue is that it doesn't seem to maintain the connection when idling. I'm using a Canon T5i, and on that side, everything is fine; the camera recognizes the card and it stores the images just fine. On my iPad, though, I have to keep it on if I want to see the images being transferred without interruption. If I turn off the screen on the iPad for a little bit, it loses the connection to the Eye-fi and goes back to whatever wifi connection it was on, which, if the service is enabled, it will also start transferring your pictures to the Eyefi Cloud. What's really annoying is that if I want to continue transfering pictures from the camera to my iPad, I have to go back to the iPad settings and reconnect the Eye-fi and then go back to the app. The only workaround I can figure out is to make the iPad forget my wifi network so it will only re-connect to the Eye-fi card. Of course, that will mean I will have to manually re-connect to my wifi when I want to tranfer picutres to the Eye-fi Cloud. You would think this stuff was designed to make it convenient...

Another problem is that I can't rely on the images on the app to evaluate detail or focus when zooming in, so this means its best for you to view the images without zooming in or you might think you took a picture out of focus or you moved when taking it. Fortunately, the quality is preserved when the images get moved to the Eye-fi Cloud, and on the card itself. I suppose this was done to speed up the transfer time.

Other Thoughts: I wish Apple would have came up with its own type of wireless transfer card that was guaranteed to work seamlessly with it's own products.

Or maybe let the card connect to the internet and you would see your images on a mobile device on the app after the card is done uploading them. I know that's a more roundabout way, and it would probably take longer, but it might still beat having to pull out the card from the camera and connect it to an iPad, or wait to get to your PC and use a USB transfer cable to get the images out of the camera.

Or use Bluetooth since most devices can use Bluetooth, Wifi and Cell networks at the same time. So you can view the pictures at the same time they are being uploaded elsewhere. Although I figure that might kill the battery more quickly... Oh well, I guess something had to pay the price for convenience.

Pros: I have had a Eye-fi Mobile X2 for over 3 years and it finally stopped working. I used it fairly often, and I think I just plain wore it out. Shooting up to 120 fps at baseball games and transferring a ton of photos will put a little extra load on this baby. I sure got my money's worth though.

So now I am upgrading! Looking forward to the added performance from a class 10 card. When I bought the first one class 6 was as good as it got for the Eye-Fi.

I actually have one of these already, I gave to my mom as a Christmas present this year. I configured the software to direct connect to her cell phone. So she shoots a picture with her incredible Nikon camera, and within a minute or two it is available in the gallery of her Android smartphone to share via text, email, facebook, or whatever. Then, and here is the really cool part, those photos will sync to a NAS drive on her home network from anywhere in the world! (that's not a feature of this product, I made that happen using other software and apps but with the right gear you can do it too).

The endless memory is enabled on the card in the camera, so she never needs to find the camera cable or a card reader again. The phone will automatically upload whenever it's in range of the home wifi, and it can upload over the cell network if she chooses. I haven't found a way to auto delete uploaded images from the phone, but it's no big deal. Once every couple months I just check the oldest pic and newest pic on the phone, check the folder dates on the NAS and they line up every time. So then I just delete the images from the phone, knowing that they are safely stored on the NAS where she can edit them on her laptop or desktop. An occasional backup to a 128 GB USB stick and I know that all 30,000 of her pics are safe and secure.

She loves taking group pictures at parties and waving away all the people that try to hand her cell phones and cameras for pictures. She just snaps a few pictures and sends the pic out to 5 people, who each send it to 5 people that send it to 5 more and in a couple minutes everyone has their own copy on their phone. And in much higher quality than if they had shot the picture with a phone too.

I love it because she ins't losing the cards, or duplicating images because she forgot that she had imported them already. Twice. I organized her mess of a pictures file a couple months before Christmas and I weeded out over ten-thousand duplicate images. They were taking up space, slowing backups, and cluttering up the library. With this configuration it's simple. Point, shoot, share, save.

Cons: Mine eventually died. It's a minimum of three years old. I took thousands of shots with it.

NOT COMPATIBLE WITH ALL CAMERAS! so do your research before jumping up on the bandwagon.

The configuration is tricky. Really irritating if you don't have sold tech skills. The card can only be configured on a computer, so don't expect it to be magic right out of the box. You have to check each setting for each device that will be used. And you have to be sure that the app settings on the phone/tablet are in line with those on the card and in the computer. It will not work otherwise. It might not transfer at all, or it may duplicate files. I think you can even send pics from your phone to your camera if you really bungle it up.

The phone interface on Android is particularly annoying. It doesn't always make sense what happens when you make a change. Another setting may be undone in a different menu of the app. My advice is to try to use the phone as the middleman between the camera and computer. That way everything flows one direction, and any pics you take with your phone just get added in on your next upload, which should happen whenever the phone is connected to your Wifi.

Other Thoughts: Think I'll go have a sammich.

Pros: Easy setup, Quick transfer of files. Battery life in my Sanyo camera is good so I really haven't had a problem with wi-fi running down the battery. Photos and 720p or lower videos are excellent on Apple devices.

Cons: iOS app does not transfer or play 1080 videos. Not a big deal.
