The Black Mirror BASIC+ improves on the Timemore's excellent Black Mirror Basic. The BASIC+ won't accidentally get turned on or off, with the addition of a physical power switch. Its reconfigured, internals result in more reliable measurements in less time and texturized buttons allow for touch recognition in low light and differing orientations.
