Update 5÷3÷16: We used these people for about a year. Their success rate is poor. Avoid«stakeouts» where they ask for $ 450, «virtually» guarantee success, and then fail to serve the party. And when you express frustration with their poor service, expect them to ignore all subsequent emails and screen your calls. The business response is blustery nonsense with no basis in fact. The Illinois Attorney General needs to take a good look at this firm. «5÷4÷2015 Please be advised this review is false and defamatory traced to a malicious person who is currently under investigation. Legal action is pending and this libelous individual will be responded to accordingly.» My opinion is that these guys are scam artists.
