I like that it is free to create an account even if you don't have any domains yet! It's great there are so many suggestions in different price ranges as well (and not just $5 ones!).
Sometimes typing something into Google brings up too much noise/results which makes finding what you're looking after difficult or time consuming at best - but this doesn't happen often enough when using other more specific tools such as Domainr & CoSchedule / Nameschema etc.. However they do offer some really nice premium plans where things start getting better than google searches alone e.g., additional filters by industry type, number keywords used within your chosen term(s), ability to add contact information from social media accounts directly onto relevant submissions via API integration would be very helpful though maybe costly? Also adding option similar to "related" results could save alot of searching through all entries again.
