This company is running a SCAM - selling analog boxes which "technically work" only problem is no one broadcasts in analog anymore. The government mandated that all signals go digital back in 2009.
Thet hide the fact that this is an analog device and will not work with digital signals.
They claim that the unit works with all cable providers when none of the providers still use analog signals!!!!!
Don't try to communicate with them all you will receive is old man verbiage about putting water in a gas tank or some other useless analogy.
Bottom line is DO NOT TRUST THIS COMPANY!
