Crafty or Wot review for 404/301 SC Easy URL Redirects

not managed to open the app so far so cannot comment Following a session with Anes I am now up to speed with this app and it looks like this is just what I needed to correct thousands of old mistakes that created 404's (google is not happy) my lack of knowledge and many redesigns of my site with out a single redirection has given me this back log. I hope now I can reduce the problem using Easy redirects
