The signal rejection is horrible. That is to say, I set it to my favorite NPR station and another station 11.5MHz higher booms over it. I did this experiment right next to my Sangean clock radio, and I also tried the (Great) GE 7-2887 Portable radio. The non-Philips units worked perfectly, so it wasn't some anomaly wth the ionosphere (unfortunately, they aren't water proof, and make no claims to be). So I opened the back up (where the battery compartment is) to have a look around. Although the batteries themselves were dry (there is separate seal for them) the screws that hold the radio together were rusted. I bought this unit in November and it's rusting--this in a product built for use in the shower... So, buy it if you want to hear multiple stations at once, and don't get it near water.
