      Excellent value with an impressive feature set.

      Overall: 4.5 out of 5

      This instrument has every feature the on-line description mentions, thoughtfully implemented. The display is expecially clear, and evenly illuminated by the switchable backlight. Not mentioned were the included 9-v battery and the decent case with a nicely fitted foam insert. No complaints at all, but a couple of enhancements would be appreciated. The instructions say to remove the battery when the meter is not to be used for a time--a prudent suggestion. However, this means that the recess in the foam insert for the battery will be occupied. A second slot for a (user provided) spare battery would be nice, and should add little or nothing to the cost. Also, the battery compartment cover is secured by a small, Phillips-head screw (mind you, a machine screw with a threaded metal insert in the body). I would be neat if they included an inexpensive Phillips screwdriver with its own slot in the foam insert.
