The simultaneous observations from Spitzer and the ground yield measurements of the microlensing parallax vector $\\pi_{\\rm E}$, from which compact constraints on the microlens properties are derived, including $\\lesssim$25\\% uncertainties on the lens mass and distance. With the current sample, we demonstrate that the majority of microlenses are indeed in the mass range of M dwarfs.
