If I read their about page right, they only check your mail a few times a week (3x), then if you decide you do want a specific piece of mail they've scanned they will send it back to you. So you still end up checking your mail waiting for the returned item and having to filter through any junk mail that hasn't been picked up yet. This is not something I would pay for or even do for free.
