The wp-301-redirect plugin works superbly, that fact that you get a license for 10 sites for Free is an absolute bonus.

The fact that it includes redirects to the correct page on typos is absolutely amazing. This part works as if by magic, out of the box without any additional configuration, and is a major bonus. I have it configured on 3 sites at the moment and plan to add it to my other sites as soon as possible.

Being able to control everything centrally, from the dashboard, is a major time saver. Absolutely marvellous and an absolute must for all webmasters and agencies.
