Digital appliance fine (all I need to change) (4,4)

Ross

I think it could be either:

Which length description are you looking for?:

8

4,4

nail file

'digital appliance' is the definition.
(digits can mean fingers or toes)

'fine all i need to change' is the wordplay.
'need to change' is an anagram indicator (I've seen 'needs to change' mean this).
'fine'+'all'+'i'='finealli'
'finealli' is an anagram of 'NAIL-FILE'.

(Other definitions for nail file that I've seen before include "Manicurist's tool" , "Bored receptionist's grooming tool?" , "Metal strip to manicure fingers" , "instrument with digital application" , "Final lie (anag.)" .)

I've seen this clue in The Guardian.
