The wallet works as promised. +1 to this user.

EDIT: Hi, I just want to add a tutorial for Newbies who don't know how to use a custom address but wants one.

After doing the procedures mentioned from the OP,

1. Go to blockchain.info. Log in your account if you have one. Otherwise, create a new one.

2. Go to Import/Export and click I understand.

3. After that, Enter the Vanity Private Key (WIF) which was given to you in bitaddress.org.

4. Select Import Directly if you want to add the custom wallet to your blockchain account. If you only want the balance of your custom wallet to send to your blockchain account, then select Sweep Key
