I think I got the same one that you did. And for a iPhone charger/cradle/FM transmitter/Hands-free for the car, it works pretty good.

It was <$27 (CAD) including shipping from my bank account via PayPal and I ordered it on the 16th, and it showed up on the 24th from Hong Kong. The bendy arm is good so I don't have to pickup the phone to change to the next song. FM works...better than I thought. Not fantastic but is completely able. The Hands-free my buddy said I was clear, a little like I was in a tunnel but he could hear me fine. It also has a nice tight squeeze with my Switcheasy CapsuleNeo case that I keep on my phone.
Only problems I had were if I left the phone connected in the car and turned the car off when I turned the car back on sound didn't work. To fix I just unplugged the minijack cable and plugged it back in. And once the FM station I previously used didn't work, autoscanned to the next one and it was fine. (I made a lot of short trips yesterday)
I did not hear any annoying beep that people were talking about, so that was cool. Basically, if mine broke tomorrow... I'd go buy another one.
