For around $20-25 bucks it ain't bad, but it's really not better than a good fm tuner. I had the zune hd for awhile and the hd radio was pretty good. On this unit you're lucky if you're able to get a station in hd. Hit and miss. Even if it picks up on hd signal and moves off fm, it isn't any better. It's decent for $20. They also have a newer model that has a touchscreen, but from what I've seen it's worse than this model. The only other portable hd radio is made by JVC. It's for around the same price and from what I've read around the same quality of the insignia. The insigina doesn't and tagging and I don't believe the JVC does either.
I use the insignia tuner for probably 10 or more hours a week and reception is acceptable to me. Oh, and you're not the only one surprised from the lack of portable hd radios.
