The Double experiment was one of three reactor neutrino experiments which sought to determine the then unmeasured neutrino mixing angle theta-13 at the beginning of the decade. It first ran with only its far detector, and indicated in 2011 that theta-13 was non-zero. Subsequent measurements by Double Chooz, RENO and Daya Bay have confirmed this. Now Double Chooz also has a year's worth of data from its Near Detector, and is presenting two-detector results for the first time. The data, backgrounds and systematic errors are shown, and the neutrino oscillation results compared to those from Daya Bay and RENO. Implications for future neutrino studies are discussed.
