    In a recent letter,1 it was reported that a magnetic tunnel transistor ~MTT! with a spin-valve base can exhibit high magnetocurrent ~MC! as well as output collector current in the microampere regime. While the presented experimental results are sound and unambiguous, the comparison with the spin-valve transistor ~SVT! is not. In this comment, we wish to address this by separately comparing the output current, transfer ratio, and MC of both devices.
