5 out of 5 eggsOld Car is Bluetoothed

Pros: Plug in, set station, paired them, set radio station button, away I go.

I'm a much safer diver, hands are 10 and 2 or 9 and 3 or 1 out the window and the other keeping the dumb beat.

Cons: I still afraid some is going to sneak up behind me when I'm drink from a water fountain and push my face in the water.

Other Thoughts: Teenage daughter will pair her Itouch and my ears will bleed from that noise.

5 out of 5 eggsWorks great

Pros: Plays music from my phone, switches to phone automatically, pauses when turned off, sound is good as long as you have a clear radio station, voice is so-so but that's not why I got it, on sale for 39.99 when i got it

Cons: None so far, as for the people that say theirs is falling apart I have one question, what the hell are you doing to it? plug it in and don't touch it

5 out of 5 eggsGood, easy fix for last generation of cars with out AUX line in

Pros: Easy to setup and drive. Reconnects automatically and when it doesnt (which bluetooth will do occasionally) it is easy to troubleshoot and reconnect in seconds. Will charge phone.
Bluetooth connection sounds better than line in.

Cons: If you ever turn off car and turn on battery only and then turn key to start or turn off again. Vice Versa. It can sometimes forget the FM station you have selected. This has only happened a hand full of times over a 2 year period.Will charge phone but works better without anything drawing power from it.

Other Thoughts: pretty easy to change stations but long road trips in and out of cities will cause you to change FM stations more than you want to probably.

2 out of 5 eggsDisappointing sound quality

Pros: - Bluetooth connection works well - no synching issues
- I like the added usb port for charging
- I like that it has an on/off switch

Cons: Sound quality is terrible. Every time lyrics contain an "s" it comes through the speakers like the sound of static from an untuned station. This happens on all FM channels at all volumes.

Other Thoughts: Very disappointed. I purchased this thinking it would be a premium FM transmitter with good sound quality. Instead I overpaid for an under-performer. I would not recommend this product.

Maybe my experience is due to the combination of car and transmitter. I'm using this in a 2006 BMW wagon. Since other reviewer seem to have had better luck maybe it works better with other cars, but if you have an older BMW without Bluetooth audio steer clear of this product.

3 out of 5 eggsFlexSMART X3 So-So...

Pros: Small form factor, buttons well marked, fast to pair with my iPhone4, can tune its FM transmitter to any FM band frequency manually (if necessary), better than average FM sound. The built-in USB 5V socket almost compensates for the device 'stealing' the only dash-mounted 12V accessory outlet in my 2000 minivan.

Cons: My big worry prior to purchasing this particular BT-FM adapter was something repeated in other reviews: Poor Microphone Audio Quality. I will add my voice to this same complaint. With hands-free phone calling a big reason for owning a device such as this FlexSMART X3, it's very important that the person at the other end of the connection be able to understand what's being said. After testing the outgoing audio quality by recording a message on my home phone voice mail, the playback revealed a low level, distorted, clipped and almost impossible-to-understand audio.

Other Thoughts: I needed a suitable replacement for my Motorola S505 Bluetooth-FM transmitter and read many reviews before finally settling on this one. There was that 'hope' in the back of my mind that my X3 would be one of the better ones and *not* suffer from the poor phone call quality as has been reported here all too often. So I can't recommend the purchase of this device if hands - free calling is the primary use. It's fine for music playback however.

I'm open to communicating with the manufacture if they want to help resolve the phone sound quality issue.

5 out of 5 eggsWorks better than expected

Pros: Better than expected sound quality out of a FM transmitter. Provided better sound than my integrated satellite radio puts out. Easy to setup, charging ports built in. Voice calls are clear.

Cons: Requires a bit of channel scanning for the best feedback. Sometime voice is a bit low in volume.

Other Thoughts: Great device, I have used it in a Audi Allroad and Infiniti G35X that do not have a aux input stereo jack. I haven't had good results with many FM transmitters, but this one is an exception. Both cars have a bose sound system and the transmitter provided better sound quality than the cars built in satellite radio option
