Input:
I am a fan of the orginal Polder 898-95, and recently purchased second.  Amazon Prime quickly deliver the newest version.  The new version is both a disappoint and frustrating.  The keyboard buttons are now recessed and frustrating to use.  It now requires a finger nail, pencil point or paper clip to make a number entry.  Polder took a well designed and easy to use timing tool and degraded (cheapened) the ease of use.  Still a great design, 'made in China' poor quality.  2 1/2 stars.
