5.0 out of 5 stars Finally, a Class 6 SDHC card from Eye-Fi! April 4, 2010
Style Name:PRO|Product Packaging:Retail
First off, there are several different Eye-Fi models so I suggest you get the one with the features you need. The "X2" models now have the Class 6 rating which is great news for fast D-SLR's with high megapixels (18+, etc) or taking 1080p HD video to ensure the data transfer rate can keep up with the recording.

The X2 adds the Class 6 rating, 802.11 b/g/n capability and endless memory. All of which were major concerns with the older models when using them in modern D-SLRs.

I chose this one because the X2 Pro offers RAW image transfers and Ad hoc mode. If you do not take pictures in RAW format and/or do not care to transfer directly from Camera to Laptop via WiFi, then get the X2 Explore for $50 cheaper.

Setup is a breeze. When you first put the card into the computer, it will ask if you want to install the software. You can use the web based settings manager if you do not want to install any software. I chose to install the Eye-Fi Manager software. Very functional.

The first thing it will ask you to do is to select a network to connect to. I chose mine at home and configured the WPA2 security in seconds.... it connected and asked me to put the card into my camera and take a test picture.

I did so and withing seconds, my T2i's display showed that the eye-fi was connected and transferring data. The computer software system tray icon lit up and confirmed this too.

I took an 18mp picture for the test which turned out to be about 22mb RAW and 7mb jpeg. It finished the transfer quickly.

There are many custom features you can set to tell it what to do with the pictures. I have mine set to transfer to my HDD and MobileMe account. There are about 25 online services you can automatically upload to.

Style Name:CONNECT| Product Packaging:Retail|Amazon Verified Purchase
Product works exactly as advertised, and is very convenient to have and I'm glad I bought it. It's easy to configure and exceptionally easy to use.

But I have two gripes about issues that I didn't discover until after I got it (but which are well-documented on Eye-Fi's website):

1) With my camera (a Nikon D40), the camera won't leave the power on to the card long enough after a picture is taken, so the pictures don't get uploaded. The workaround is easy - turn the camera off and back on. But it's annoying to have to remember to do that, because that's the point of the card - to not have to think about it. (Of course, this is really Nikon's fault, not Eye-Fi's, but it affects me nonetheless.)

2) The Eye-Fi has a feature that lets it upload both to a home computer and to a website (like Flickr or SmugMug). I knew that the Eye-Fi supported doing the uploads also to an FTP site, and I planned on using that feature to let it upload pictures to my home web server from anywhere I could get a wi-fi connection. It turned out that there were a number of problems with that plan:

a) It only uses "FTPS" while "SFTP" would have been much easier for me to set up, and much more secure

b) The pictures all go through Eye-Fi's servers before going to the FTP site, which I didn't realize (and this part isn't especially well documented), and I'm not OK with that

c) It takes a long time for the pictures to actually make it from the card to Eye-Fi to the FTP server, so it was very hard to trust that the system was working reliably

d) There's no way to tell the Eye-Fi to then NOT upload the pictures via my home wifi, if they were uploaded via FTP.

So I just don't use the "upload via FTP" feature, and that's fine.

3.0 out of 5 stars Great hardware, but the software needs basic help April 19, 2010
Style Name:PRO| Product Packaging:Retail|Amazon Vine™ Review (What's this?)
Here is my experience. Harware 5 stars, software 2 stars. Average 3.5.
Installation file is 21 meg, hardly what I would describe as a compact file (per the manual). Installation offers updates to both software and hardware(firmware) Software is now 3.0.20 version, was 3.0.16. You also must then also allow Adobe Air Installer to access your computer, for non personal data only. Not quite sure what that does, maybe the web based geotagging. Then the SD card updated its firmware from 4.1010 to 4.1012. As installed the software is 12 meg total on a WinXP PC. Took 17 minutes. Reasonable.

Now taking pictures! It takes about 5 seconds for a 850 meg 7 mpixel photo upload. This was at about 50 ft distance from my N router. Right after the picture is taken it appears on the screen. By the time I took my test pictures outdoors and ran back inside to look, they were all there. Software allows to upload to any directory, but defaults to My Documents/ Pictures. Eye Fi helper software which does all this housekeeping can run in auto mode or you can manually start it. Geotagging works great, when you click on the thumbnail it shows a small Google map with the location of your photo. Once again this function is dependent on a Sky Hook recognized wi fi mac address hardware being in the vicinity of your card when the photo is taken. I loved everything so far. But..

Glitch one. And a bad one. Bad or test pictures are forever. A total of 10 photos taken generated a 1 meg log file, a 8 meg dated photo directory, a duplicate "spool" directory of full size photos, and a cache directory with thumbnail snaps. Tons of overhead. Should not be a problem to clean up. Wrong.
