Back in January at CES, the gaming-hardware company Razer jumped into the wearable technology race with theirannouncement of the Nabu. When CES ended, the Nabu was something we were eagerly awaiting, but since then news of the wristband has died down. Part of that silence is due to the fact that Razer had to delay a previously announced beta preview of the product to make sure that it was fully hypoallergenic. The last thing Razer wanted to encounter with their new wearable was a situation similar to that which required a recall by Fitbit. Razer is coming back swinging today by announcing an open beta for the Nabu – they are looking for fans of their products to test it for them.
