What makes the LuMee different from other cases is the light it produces that bathes the selfie taker in a warm glow. This helps the selfie look like it was taken by a professional. The case is equipped with two vertical rows of LED lights, like the kind you might find on a vanity mirror. The brightness of the LED's can be adjusted by the user to make sure that he/she is snapped in the best, ahem, light.
As we said, celebrities have gone gaga over the LuMee including Kim Kardashian, who has been photographed using the case. And as you can imagine, sales are booming thanks to word of mouth.
There are some caveats. You can't sneak up on someone and take a selfie because of the light, and the light also brings attention to the selfie shooter. At $50-$60 the price of the LuMee $50-$60 makes it a stumbling block for some.
