Question: why did the price double?
Document: Returned this radio for two reasons: one, my digitally-handicapped husband could not use buttons to change stations; and two, the reception for our area FM station was poor/no better than our previous radio. Also advise anyone interested in purchasing this from Amazon to check prices elsewhere. Amazon's price was double that of Best Buy.
Amazon sells this radio for $99.68 not including shipping.Yet the manufacturer's suggested retail price is only $51.99 ([...]Best Buy sells this unit for $51.99 ([...]I never thought Amazon would rob me--that is, charge nearly double MSRP! Sure, it may be sold by Amazon through one of their partners, but Amazon's due dilligence should include not allowing items to be sold at a cost greater than MSRP.1 star for the price.
We found the Insigna HD Radio to be a very good product for the price. It's pretty clear and gets good reception.
Reception very poor for both fm and fm hd. Not worth the price. Compared to my old am/fm from the exact same location reception is horrible. I would not recommend this radio.
It brings in HD signal and sound very well for it's size.Plus it scrolls the song and artists name in a digital format with a blue background,make's it very easy to read.Price and quality...in the zone!
The sound is good but it won't satisfy an audiophile. For that, you need to spend about four to ten  times more. Also, if you are in the boondocks you may need to get an antenna for good reception. All in all, this is a great deal and at this price the only game in town.
I have HD radio in my car and have enjoyed an oldies station without commercials here in the SF Bay Area while driving. But the signal is weak and the radio is &#34;searching&#34; as much as playing the music. So I got this for at-home listening. Signal is great and the radio is so convenient. It can be plugged in or used as a portable. I am surprised it works so well for such a low price!
Relatively sensitive receiver. It does need the external pigtail antenna to pick up some local stations. Has mediocre low frequency response but plenty of preset settings. For the price, this is a good receiver for the kitchen or a desk at work,near a window where you can get signal. I do wish it had more front-end RF amplification so it could pick up stations further away.Three honestly earned stars.
I've been looking for an HD Radio I could take to my office. This radio is the only game in town. I've looked for others. I have a Sony HD radio Tuner connected to my receiver in the house. I'm not sure why HD has not caught on. There are lots of stations in major cities broadcasting in HD. Shop around. I would have preferred to buy this at Amazon but the price differential forced me to look elsewhere. I would not pay $100 for this radio just as I won't pay $300 for Bose headphones.
Don't let the small size and price keep you from at least considering this item if you are looking for a portable HD radio. I had been thinking of getting a small portable HD radio for a while. We are in the fringe coverage area of two local public radio stations. The tuner in our old analog radio kept drifting and losing the signal. And because one of the stations is at 88.1 MHz, the default channel for FM modulators used with a lot of portable satellite radios, passing cars or trucks with an overboosted modulator frequently blocked the signal from the old analog radio.
Answer: I have no idea why the price doubled (from when?), but it's normally $52 at Best Buy, and it's on sale at Best Buy now (11/20/13) for $40. Same model, I just bought it.
