I have had a t-box for about 6 months now and have had the usual freeze ups, but I can live with that. Since reading about these units on the internet it's hard to find anybody with anything good to say about them. I have a question. Is it ok to unplug them every night to save power, or is it bad for them. Plus my t-box made a screeching noise the other day, but it seems ok now ?
Thanks
