Real effectiveness of a nandroid backup by cwm

[Guest d_borghi]

hi all,

very often i change the rom of my chinese zte blade, and always after a nandroid backup of the actual rom.

when i want to return to a previous rom i restore it from a nandroid backup made by cwm.

but very usually after a restore, the s.o. seems to have some trouble (fc, sluggish, etc.) tha it was just fresh installed.

It is only my impression or is it real?

tnx

Every time I've restored a nandroid it's been exactly the same as it was, I've only restored maybe 10 times at most tho.
