Easy to operate (4-8)

I believe the answer is:

user-friendly

'easy to operate' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for user-friendly that I've seen before include "Easily picked up" , "Easy to understand or manipulate" , "Easy to operate" .)

I've seen this clue in the Family Time and The Guardian.
