Product: Eye-Fi Connect X2, a camera memory card for wireless photo and video uploads.

Features: When the camera is turned on and in your Wi-Fi hotspot, the Eye-Fi memory card inside will send the photos and videos you take to your computer. It also can send files to several photo-sharing websites, including Facebook, Flickr and Picasa.

Price: $49.99.

Ups: No need to ever connect the camera to the computer to back up your pictures. Just turn the camera on when you enter your Wi-Fi network, like at home, and it starts transferring. You don’t even need to have your computer turned on. The photos will start uploading to the computer the next time the computer is on and connected to the Internet.

Downs: Because this has Wi-Fi technology built into it, this memory card will drain your camera’s battery slightly more than a regular card when it transfers files. And transferring a large video file can drastically drain a battery in minutes.

For it to transfer photos, you first need to connect the card with your laptop and program the Wi-Fi network’s name and password into the card. So unless you have your laptop with you, there’s no way to log in to any Wi-Fi network you stumble upon

Bottom line: The technology is pretty nifty. But aside from the benefit of never having to plug it into your computer when you get home, it’s more worth the cost for someone who wants to share photos often online and who also carries a mobile hotspot with them — since you probably won’t be taking your laptop along on most trips.
