I did. I went that route mostly due to the free consultation button. The agent assigned to us was fairly good, but was probably overwhelmed with multiple houses for sale, and communication was somewhat lacking. I went with a different realtor, one I knew personally, for buying; I should have gone with him for both sides, he's very good, friendly, and calls multiple times a day when needed. Our house wasn't expensive enough for the area for redfin to be involved, which is why we got a partner agent.

Overall, I like Redfin for looking at potential houses, but it needs something more, IMO. Like offers and other details on their website (account dashboard right now just links to your listing, nothing else). Maybe even an electronic signature feature for offers, etc.
