can you suggest a really good electric foot file?!

Ive got the schol one and a boots own brand one but for whatever reason they dont seem to have enough power...... i dont think its the roughness of the file, its more the power of the gadget that doesn't spin the file around enough so it just tickles feet rather than file them iyswim.

I've tried the exfoliation socks which re great but i cant face the two weeks wait of peeling.
