I saw this a little while ago and recently my friend ranz purchased two! What is is? It’s like a softbox in the shape of a tube. It is is portable, lightweight, modular, and is to be used with your small flash units. Right now they are on a reserve/preorder status for $135. See all the specs, results and configurations at saberstrip.com.
