I can't really give a good review as I only had the NS-HDTUNE and didn't have it for very long. Controls were good, it tuned everything (but then, I had it hooked to the rooftop antenna). However, the unit I bought exhibited a noticeable shatter in the high frequency range, analog and digital, all stations. I'm guessing that's a bad amp, so I took it back. They didn't have a replacement and I've yet to get another one. That's not a reflection on the unit itself as much as it is my procrastination.
