I've tried at least 3 other expired domain services and this one is by far the most updated, easy to use one out there. Every other one I have tried is somewhat confusing even if you have a lot of experience with buying domains. I like to look for ahrefs DR and Moz Spam. Then I like to search for anchor text and particular referring domains (like Wikipedia). DomFinder makes this super easy. I can search with a saved search and also get email notifications daily for new domains that match.
