I used this card in a Canon A560 point and shoot camera using a Windows Vista 64 machine on a protected wireless G network. Setting it up was very easy. Pop the card, inserted into the included card reader, into a USB port, and follow the prompts. When the software is installed you have to register the card via a web browser with the Eye-fi website. They asked for an email address, your name, and a password. I put the card in my camera, took a picture, and voila, the picture was downloaded to a new "Eye-Fi" folder in my pictures folder. The pictures download as soon as you take them and these 7.1MP pictures took about 3-5 seconds each to download.
The good:
- Easy installation
- Works as advertised
- 4GB stores a lot of pictures; pictures remain on card just in case
- No cables needed
- Uploads to picture sharing sites
- Amazing that it works!
The not so good:
- No control of when pictures download. If there are new pictures and your computer is on, they download. So you don't get a chance to delete the bad pictures from the camera before they download.
- It is a bit slower than a cable. If you have many pictures to download (say you took them away from your network), you have to wait longer than if you used a cable. Again, if you only wanted one or two pictures, you still have to wait for them all to download.
- You have to leave your camera on for them to download. Although there is no cable, you still have to wait for things to finish so you can turn off the camera and put it away.
- It is unclear how much power the card uses so I don't know how it will affect battery usage.
- At least thumbnails are uploaded to the Eye-Fi website whether or not you want that.
Maybe it is just a habbit of ours, but without this card, we download just the pictures we want to a folder, and then file them away. Usually we do this after an event (birthday, outing, etc.) so it is pretty easy to decide where they go. With this card, the pictures just pile up in one folder and you have to sort it out separately, including ones you'd never had transfered in the first place.
There is also an extra step of making sure all the pictures downloaded wirelessly before you clear the card. With a cable it is pretty clear; you just downloaded everything you want so you can now clear the card. With the Eye-fi it isn't so clear unless you are in the same room as your computer and watch things happen on the screen.
If you aren't uploading to Flikr or the like, it is uncertain if this is a useful product. A cable can be left attached to your decktop or left on your deck where you use your laptop. The time it takes to connect it is more than made up for by the speedier downloading and spending less time making sure everything downloaded.
I imagine if you do use Flikr and the like, this is great in that if you are traveling, folks you share photos with can see you photots. But, again, unless you can access your account, they are going to see all of your photos if you don't delete them prior to entering a wifi hotspot. Apparently it works at MacDonalds and many other places. Good that it happens so easily, not so good that it might happen when you don't want it to. I imagine that, while traveling, deleting would be easier since you are more often than not away from wifi.
One last caveat: whether or not you sign up for online services, the Eye-Fi website gets, at least, thumbnails of all your pictures. I used the card on my home network assuming it would just go form the camera to my pictures/eye-fi folder. But when I went to change some settings, I was taken to the Eye-fi website and was presented with the images that just downloaded. You can remove them, but it seemes like you should be able to use this card without that happening if you use your home network; I assume, and it makes sense, that it has to go through there servers if you use the web services (e.g. Flikr), but why is that needed when it is all local? Just another thing that makes me feel not everything is in my control.
****** New/Additional Comments ******
Customer service left a comment with my review and, in the interest of being fair, I'd like to point out their response as they tell how to address some of what I consider the shortcomings. Apparently it is very easy to set up but there are more advanced features that can be used but which you have to explore a little more to implement. I should point out that their replies to me and others are very polite, well written, and informative which makes me think well of this company.
1) Pictures don't have to download automatically. You can can set it up so only ones marked as "protected" on your camera will download. Most camera's have this although I never use it, but this would be a good use for it. "You can read more about it on our blog: [...]
2)It isn't just one folder but a folder for each date. That is better but still not the one folder per event one usually makes if doing this by hand (we have on folder per month with special events in a subfolder).
3) Customer service says the thumbnails are not sent to their server and, from what I can tell, they are right and I was wrong. The URL has a IP address that must be that of the card and not their server, which is what confused me. This takes away a big objection. "You can test this out by logging in to your account from a different computer - you won't find the thumbnails there."
