Reviews
Pros:
Small, lightweight
Has a backlight
Touchscreen makes entering numbers faster and easier
Cons:
The LCD screen unfortunately does not offer a very good view of the numbers; the poor quality of the screen means that you cannot look at it dead-on, you have to view the screen at an angle (from bottom up) to see anything, and the backlight needs to be turned on at all times simply because the characters are not black enough. Everything is mid-to-light grey which makes things very hard to see.
