Static Free !!
I've bought several brands of these FM transmitters and they all had issues. From poor reception to decreased volume. This one has a built in volume which increases the signal and eliminates volume discrepancies. I use 89.1 fm and this has never lost signal or had interruptions. Being able to turn the knob and search through your music library is a feature I've used more than I thought I would. Definitely recommend, it is a good value for cars without Bluetooth capabilities.

A brilliant solution
I bought this transmitter just before going on a roadtrip with my husband. In the past, we used a battery-powered version that connected to a device via an aux cord and dongle combo. I wanted something with multiple usb ports that would enable me to play music and navigation through the stereo, without rendering one of the car’s two cupholders useless (the only outlet is, annoyingly, right above one of them). I picked this gadget in particular because I like the brand, and because it ticked all the boxes. Plus, it doesn’t have crazy RGB lights, and the display is bright enough without being distracting at night. It’s simple, practical, and easy to use. The best part? It has a physical knob! I don’t have to fiddle with the phone to pause or skip music, even when we have navigation going at the same time. That is a major perk.

Good purchase overall
Works great for playing your music. The Bluetooth version when it comes to talking on your phone is still lacking a bit. Others have a hard time hearing you at times.

Absolutely love this
Very easy to install, has two slots for changers and the sound quality is great. Takes up a radio station spot but that doesn't matter to me. For a car that doesn't have Bluetooth this is an amazing product to get

great Product
Easy to set up - works great. Very pleased with this purchase. If you have an older car with no mp3 input, this is the tool you need.

Static noises
Hello, I was in the market to buy a new one of these, since someone broke into my car and stole the previous one that I had from another brand. The volume even at the highest is pretty low, and there's constant static in the background. I tried different channels, and regardless, the static is there. So I'm deciding to return this one and I picked up a different model from Target and that one is working better.
