Scosche BTFM9 FM Bluetooth Transmitter Car, Dual 12W USB-C and USB-A Charging Ports, Fast Type C Car Charger, Wireless Radio Bluetooth Adapter, Hands-Free Car Kit for Calls, Siri and Google Assistant

I did not expect a FM transmitter to be this awesome. Mind you, I haven't used one for more than a decade, but I bought an old Saab as a project car, and figured an FM Transmitter would be better than nothing until I can figure out how to hack Bluetooth directly into the head unit. After a week with this, I'm not sure I'm going to bother with any hacks: It sounds great, it works exactly as you'd expect (easy to change station, easy to pair to Bluetooth, easy to re-connect), provides two USB ports for charging devices, AND has an aux-in (the manual calls it aux out, but it functions as an input) to let you plug directly into the transmitter instead of using Bluetooth (y'know, in case you want to rock an old iPod in your old car.)Plugged into the cigarette lighter directly under the stereo, I haven't had any problems with static or interference. This thing "just works" and was totally worth the purchase.

I have a broken cigarette charger and thought there was no alternative solution to listen through the stereo of my old car until I found this device. The device is very easy to use, affordable, and quality of the sound is clear! The signal strength is just as strong or even stronger than my old Cigarette Lighter FM Transmitter. Definitely worth the buy!

It seems to work well. The signal output (volume level) is stronger than most of the others that I have used. It is a bit bulky for some 12v locations.

This fm transmitter works great in my 3005 ford ranger. I initially ordered a different one on Amazon, but after about a month I started getting a crackling sound coming through the speakersThis one has worked great so far and the fm frequency gets down to 89.9, which I’ve found to be the best station for an FM transmittersThis one works great, and was really easy to pair. Super easy way to add Bluetooth to an older car with no bells and whistles

I have to say this is an excellent product! worked so well, on the calls that come in, when replying to the caller , are crisp and no distortions as well as how they come through the speakers. A great deal for folks with no Bluetooth in the car.

Here's a more formal and articulate version of your review with some additional suggestions to make it more critical:After using this device for a while, I must say that I am quite underwhelmed. Despite being slightly more expensive than other products in this category, it falls flat on many basic features that others carry. Let me begin with the physical build of the device.While the build quality is mostly fine, it is not the best. However, it's important to keep in mind that this is a sub $25 device as of writing this review. There is a single knob to change the songs that are currently playing within your phone's queue. This knob is also used when the "channel" button on the right side of the device is clicked to then tune the signal which you can pick up on it from. The main issue being that if this is the main knob you interface with, I don't understand why the manufacturers wouldn't have put a little more thought into making it feel less awful to use. It feels flimsy when moved, flipping out with little action required and then falling back into place. Although it does the job well enough, I am unsure how usable it will be in the future given the quality of it. It's likely that a cheap knob like this will give out or misread inputs over time.The light reads off the channel number with a pleasant white LED. This is my favorite part of the device, as it is very easy to read while I am out and about. However, the quality of the audio is where this device really falls short. It seems to be fuzzy and quiet at best, with absolutely no way to adjust the audio from the device. This is absolutely crucial for people with older cars, as they may require a stronger audio signal to properly listen to their music. In other Bluetooth models I have used, it is very simple to slide the volume all the way up and easily be able to listen to the music. However, with this device, I have found myself needing to turn my car's volume up to 70% just to hear what sounds like 10% volume on the FM radio. Despite checking the very brief manual given with the device and ensuring that volume limiting is turned off on my phone, the audio quality remains poor.To make matters worse, the audio quality lacks both high and low ends, making a lot of the fun or nuance of music get lost in the process. It's disappointing that such a basic feature as adjusting audio is missing from this device. Without it, the device is almost unusable. Given the fact that the audio quality is poor and the device lacks basic features, I believe this device may have some quality control issues, and you're not entirely sure what you're going to get.In conclusion, my advice would be to look for something else, as this device is lacking in very basic features to begin with, yet it is sold at a markup compared to competitors.
