(Upgraded New Version) V5.0 Bluetooth FM Transmitter for Car, 7 RGB Color LED Backlit Radio Transmitter, QC3.0 Dual USB Ports Adapter Car Kit, Supports TF Card, USB Disk, Hands-Free Call

It connects instantly which is nice, but the sound quality could definitely be a lot better. It has some buzzing and "lispy" sounds at times, but all in all it's pretty worth it.

Really neat device. Love the lights and fits nicely between my cup holders. The other devices tend to have a piece that sticks up from the connection and gets in the way for my car where as this one fits great. You do have to turn your radio up louder than a normal radio station but that has been my experience with similar devices as well

Great product if you don't want to pay for a new radio and installation. Never even knew these existed until Amazon recommended it. Bluetooth works great and plays all my music! I was going crazy listening to radio stations and my C D player didn't work! Plus it's portable if you want to play your music in another car without having to connect to their car.

Sound quality is a huge issue. You have to turn the volume up all the way on your phone or other device, as well as on the adapter, in order to be able to hear it through the radio. Then, in certain areas around the city theres too much feedback (crunchy sound) to hear the music. Overall it’s okay, but if you have the money just get a new radio in your car w a USB port.

Instructions not clear took me like an hour to figure out that you have to change the frequency before you connect to Bluetooth

This is the poorest excuse for a devise to deliver acceptable sound to my stereo not to mention the mobile phone that didn't work well either.

Depending on my mood I can change my color of my USB converter easily. Works fantastic!

This was a great buy. It works excellent and am totally pleased with all the features and the consistent functionality and it's easy to use. The bluetooth connectivity was perfect. This is a good buy.
