Been using mine for the Cleveland locals all along with the living room tv. Got my daughter's from her to use with the bedroom tv. Both have been working great. For those who may have wondered, re-scanning for locals does no harm, and does not deactivate the box.
I've been enjoying my two boxes ever since I first got them. Even though Voom's been shut down for 2 months now, I'm still using them for my local channels out of two different DMAs. They even come in handy with Dxing when weather conditions permit longer distances of RF signals to come in.
