Review:

For its number input function, a numeric keyboard can also be called as numeric keypad, number keypad or numerical keypad.

A good numeric keyboard should have the following feature:

1. big numerical keys
Big keys can reduce the chance of wrong input.

2. enough key numbers
Sufficient key number is very important for number input. It should causes unnecessary inconvenient if you can not find the number key you need.

3. retractable wire to improve mobility
Most of the time we use numeric keyboard as an accessory, if not, we don’t have to buy a numeric keyboard. Having retractable wire will improve its mobility, making it easy to carry around.

4. “000” key
“000” is very useful when you type big numbers. You don’t need to type triple before you get a “000”. With this key, can you imagine how inconvenient for you to type in if the number has twelve or even more “0”?

Plus the above features, this numeric keyboard nk7601 has another top advantage. That is the backlit feature. How will that help? Well, imaging when you use a numeric keyboard at night, will your fingers make those annoying shadow on the keypad and you sometime can not see clearly? With the LED letter illuminated keypad, you don’t have to worry about that anymore.
