I tried it at SXSW and it seemed fickle. To me it seems to be one of those devices that work when the planets align just right. And since their architecture is proprietary, I won't be able to modify things myself to try and improve the detection (or use it in other, cool ways). That's why personally, the DUO is a lot more appealing and I contributed to the DUO kickstarter.

I'm going with the DUO for a couple of reasons. LEAP has been at this for how long now, and they still don't really have a product widely available; the DUO guys seem to be ready to go *today*. And while LEAK doesn't have any plans to produce an open source driver so that I can use this device and do my own processing of the data, the DUO guys say their driver will be open source. Indeed, their hardware will be licensed under Creative Commons. I voted with my wallet - DUO
