No problem!
Those reviews made me mad. They said FM is a joke and it only gets strong FM stations. Well of course it will. The further you are from an FM (Frequency Modulation) station, the worse it is. FM is a VHF set of waves (It is a flat wave line) meaning the radio needs a direct line of sight to a FM transmitter in order for it to be strong. If you don't have line of sight, you won't have a good signal.
They also said AM is a joke. AM waves are amplitude (AM = Amplitude Modulation), meaning they form a full spectrum of a wave (wave moves up and down like ripples on water). Theoretically, you should be able to pick up more AM stations than FM, but AM tends to be picky with electronic interference. and with all the electronics people have now a days, it doesn't surprise me that they can't pick up AM stations better. AM is past it's time anyway. AM was useful back in the 50s - 70s because there wasn't all the electronic **** that we have today back then. So of course AM is not going to be good.
I know this because I am a semi Ham Radio operator. You have to know some things about Electrical physics.
It looks like it's cheaper on Amazon than on Griffin's site.
I should also mention that griffin does try to help you place the antenna out of a interference area surrounding your computer. The antenna only has a 3-foot USB cable, but they include a 3-food USB extension cable so you can get the antenna out of way from electronics. They also include an antenna extension. The antenna is the shark fin, but just above where the USB cable goes into the antenna, there is a headphone looking jack. You can plug in a antenna extension to get better reception (Griffin includes that extension). My point is at least griffin tires to help you remove unwanted interference!
I hope this helps
