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

4 out of 5 eggsDont choose if you are serious about over clocking

Pros: Good board, runs like it should. Didnt come in DOA and can handle everything I put on it.

Cons: This board will not let you modify core voltages when you are over clocking. It makes your cpu unstable around the higher ranges. On auto @ 4.0 on a 3770k it auto volts to 1.26v, when the cpu really only needs ~1.0v

Other Thoughts: Good board if you arent going to heavily over clock

1 out of 5 eggsGet the x2

Pros: Flexible neck, removable face, power button on device

Cons: This unit does not live up to the x2. I had an x2 but it was stolen from my vehicle. I went to replace the item and thought the x3 would be an even better replacement.... wrong. Static was horrible on almost any station I tried. I would use the autofind feature, and it would find a clear station, then after about 10 seconds it would start sounding unacceptably staticy again.....The only way i was able to get this item to work well was to disconnect the antenna in the vehicle, so no radio stations had to compete with the device. The x2 worked excellent with only minimal static at worst. Another annoying feature is that the bluetooth connection tries to jack the signal all the time. So if you tried to take a call using another bluetooth device or even the handset itself, the phone call will be routed to the x3 automatically within a matter of seconds. To use my bluetooth headset to take calls i have to shut the x3 off first, which is less than optimal. The x2 handles jumping between bluetooth devices flawlessly. If you were thinking about getting the x3, please dont. The x2 is the best bluetooth fm transmitter I have ever used, and can not recommend the x3. X2 ftw.

4 out of 5 eggsGreat device, one small problem

Pros: This is a great device. It works great for phone calls and playing music. The controls on the unit will pause your song or skip to the next one. Phone calls were clear adn the person I was calling had no problem hearing my voice.

Cons: The ONLY con I have with this device is a small audio lag when watching video. I know I probably shouldn't do this but I have a media center PC at home that records my TV shows. Another program "smashes" the shows down to .mp4 format small enough for me to put them on my phone. Sometimes I play video files mostly news while I am driving to work. There is a small audio lag when playing the video files. speech and sound do not match up. It's not horrible but annoying.

Other Thoughts: I think I may actually give this to my wife to use in her old mini van.
