Search zillow listing and compare asking vs zestimate price

[Alfred Uda]

Do you hire someone to search through zillow and compare the asking price vs zestimate? If so, does the service proof valuable or worth the money spent?

I find myself spending hours searching through zillow listing and using zestimate as a "market value" close enough in most cases. So, i am wondering if everyone else do the same thing, or just hire someone to do it or use a tool that does it.
