Quick and easy upgrade. Although battery life isn't as long as hoped. Approximately 3 31/2 hrs play time before needing recharge. I say try finagling it w charger port pugged in for all the time charge and no worries of Bluetooth during during your favorite song. Second function can turn your speakers into fully functional phone calls for hands free talking. A+

It'd be nice if the charging input was on the other side though so I could just leave it plugged in. Bluetooth works well. My phone shifts all over the truck when I'm driving and never seem to lose any bit of connection if it slides between the seats. Battery life is pretty good. But would just prefer to have it charge ready while its in the cassette player. (Tried flipping it but it only seems to read when it's in the cassette player while the charging port is turned around. Cool little gadget. 4.5/5 Good overall functionality and it'll save you a lot of money if you aren't looking to buy a new digital car stereo deck or just can't seem to get rid of the cassette player because a lot of the best jams you own are still on tape (like me) it still gives you a functioning iPod/Phone/Mp3Device, Etc. hook up wirelessly through Bluetooth technologies. Sweet.

I finally got fed up with trying to plug my phone into a wired cassette adapter along with a USB charging cable and trying to juggle everything. When I get in my car, my phone's in my pocket. Digging it out just to hook it up to listen to music and then having trouble when it came time to take a call was a hassle. This fixed everything. I charged it up, paired my phone, and that was it. I get in the car, turn on the ignition, and it detects when my stereo turns on and turns on and connects to my phone automatically. When I turn off the ignition and pull the key, my stereo turns off and the device powers off as well. No more than 5 seconds later, my phone detects the device being missing and pauses my podcasts. The battery lasts 3-4 hours and it turns on and off along with my stereo. It even has a microphone that hangs out of the cassette door without getting in the way and my friends report that the audio is super clear, which was an added bonus. Plus, the button can pause or resume media playback and if held it will trigger Google Voice Search. I was starting to consider buying a new head unit for my car, but thanks to this purchase, I have everything I needed for a lot less hassle.

Becaue of this tape I dont have to upgrade my stock head unit to just play music off my other devices. I has good clear reception and the mic works decent considering its near the tape player insert. Good overall would recommend for friend. Only CON is cant charge will using at the same time

The ION Bluetooth Cassette Adapter does exactly what I wanted. I went through several wired adapters, but had frequent failures of the audio cable. Sounds good. Connects easily. Microphone for phone use works well. Battery life could be better.
