Review: Know this the web site for this gaget may tell you that the radio listings information is updated every 10 minutes. That was not the case with the radio stations I tried the emarker on. The only song information I could get was "information unavaiable check back in 24 hours". They dont even promise to have the information in 24 hours. This is not the fault of emarker my understanding is most radio stations only update their play lists every 24 hours. So the problem is the misleading information provided by the emarker site. Caution if you buy this product dont expect timely information from emarker.
Polarity: Negative
True
