People who want a 4G hotspot they can have just in case, but don't plan on using it regularly or don't plan on using very much data.

Design

It's a tiny little rounded squarish thing with an on/off switch and a microUSB port for charging. It's got three little LEDs, one that lights up green when it's on, one that lights up green when it's able to generate a Wi-Fi network, and one that lights up red, yellow, or green to indicated 4G strength

Using It

When you turn it on, the hotspot will start broadcasting an unsecured—and unsecurable— network named "[Your Name]'s Karma." You can change this to "Free Karma by [Your Name]," or "Karma Wi-Fi". When you connect to the hotspot, you're asked to connect with Facebook which involves installing the Karma Facebook app. From there you're off to the races, with a complimentary gig of data as a one-time bonus on your first activation.
If you're connecting to someone else's hotpot, you'll go through a similar set up process, except with a step where you can interact with the hotspot's owner The owner of the hotspot gets 100MB too.
If you run out of data (either of you) you'll be prompted to buy some more at $14 per gig. All the data you buy is associated with your Facebook account, so you can use it on any Karma hotspot you find later on.

The Best Part

It can be free. If you don't use much data and you're out in public a lot, you can theoretically use this hotspot without ever paying for data. 100MB is plenty of data to check email, Twitter, Facebook, whatever, and you can just keep racking it up by dangling your unsecured Wi-Fi network in front of Internet-hungry strangers. Oh, and you get a free gig to start off with.

Tragic Flaw

The Facebook integration. Yes, this is inextricably linked to the best part, but it's also just dumb. If you're not a fan of Facebook, you'll find the prompts to make unsolicited and frankly weird comments on a friend or stranger's Karma activity awkward and stupid. And even as the owner of the hotspot, having it necessarily attached to that online profile can be kind of obnoxious. If you don't have a Facebook account at all, you're out of luck. Well, unless you make one.

This Is Weird...

If your privacy settings are strict enough, strangers' interactions with you seem to disappear into the ether. So they'll get that extra 25MB for shouting "hey doofus" at your wall, but the message doesn't show up on yours or theirs. Weird as it is, this is probably a good thing.

Test Notes

     The Karma 4G WiFi Hotspot comes with 1GB of data to get you started right out of the box, and it is nice to        know that this pay-as-you-go model would mean you do not need to top it up every single month, or at a              specific expiry date. Basically, each subsequent 1GB will cost you $14 after that, and if you are being the                hotspot host, your generosity would let you remain connected longer than usual since each time someone hooks      up to your Karma, you will end up with another 100MB of data, and the goodness cycle does not end there,          too. They themselves would be on the receiving end of another 100MB of data. The network of choice would        be Sprint’s 4G WiMAX.

Should You Buy It?

Do you need backup 4G connectivity, but not to use all the time? Is there Clearwire coverage in your city? Then yes. At $79 a Karma hotspot isn't too expensive by hotspot standards, but of course the real value comes in the form of not having to pay to not use it. It's not the ideal hotspot for streaming a bunch of video or something, but it can be a great backup option to keep in your back pocket in case of an Internet emergency.
