Recent tandem mirror operations are summarized. These include potential formation without sloshing ion beam injection, MHD stability, axial potential confinement, and radial transport. As a result of potential plugging, ion temperatures of 10 keV are achieved. Beta values up to 14 % are also observed, and thermonuclear fusion neutrons are detected. Suppression of drift waves due to ExB shear flows is identified as a key factor for the good radial confinement Work to be done in present-day devices and future prospects are discussed.
