Here are four complete screenshots of the filtering process - which we estimate will take anyone under the age of 50 less than two seconds to complete! - so you can see the filter in action in all its glory:
Step 1: Click on 'Rating'
Step 2: Click on 4 stars
Step 3: click on 'Done'
Your search results are now filtered
Note that in this example two agents are filtered - even one that is advertising.
