Bests & Worsts Reviews from Amazon

While the device appears to be filtering calls, it is unresponsive to the "Block Now" button or the "List" buttons so you can't see what you've blocked and you can block any new calls. Looking at it, the unit appears to be dead. Only once did the Block Now light glow for a call, so I think that number is blocked but I can't tell. Pressing "#2" to block the current call does nothing. The unit simply dies, valid calls go to voice mail and the phones have no dial tone. Waste of money.
