I am all for gimmicky tech, and anything that might look like it dropped out of a 1970’s Bond movie is always a winner with me. But what I don’t like is gimmicky tech wrapped up in real leather and then being sold at a ridiculous price under the name of ‘fashion’. So, what is the XOO X Casely-Hayford? It is a wearable phone charger, designed with the help of Casely-Hayford, that has been built into a belt with the aim to fuse useful technology with high fashion. It fails at both.
