Lightweight, huge display (25mm tall) digits on the display, very easy to read; display is backlit; "Reading stable" indicator; adjustable feet with spirit level; auto-cut-off after 5mins of not being used (to save batteries).

It also has a counting facility. For instance, you need to make up packets of beads. Count out 100, place on weighing platform, set the PCS function to "100", confirm - now, as you pour beads onto the platform, the display shows how many are there, rather than the weight, so you can count out any number.
