Has anyone successfully used AC21 for consular processing?

Has anyone used AC21 (I-485 portability) successfully for consular processing?
Could you please post your experiences?

Reason is that I have used AC21 and going for Consular processing.
Your experiences will be really helpful.

thanks in advance.

AC21 is not for consular processing, only I-485.

If you have already utilized AC21, stick with I-485.
