## Description

Product Description

Review: Great device - Had a few of these type of devices over the years and they have all been a bit of a let down. Thought I would give this one a go due to the good reviews and wow, what a difference. I have been using it now for over a month and it has worked flawlessly the entire time. No issues with bt connection but the main positive for me is that I have had no problems with interference and the sound quality for streaming music has been excellent. Then you get the bonus of the nice screen with some info on what's playing and a equaliser. Hands free wise, it always works great and I can be heard clearly by callers. I really am very pleased with this device, worth every penny and saved me having to upgrade the head unit on my car.
Review: Reliable, good audio quality. - I have owned these FM transmitters in the past and they've been pretty useless. However this one has been great. I've used it in 3 very different cars, no fitment issues. The voltage readout warns you of a bad battery, which is genuinely useful. Once set, it doesn't forget the FM frequency even if you don't use it for ages. I never have a problem connecting it to my phone. It just works. The display is good, it doesn't look tacky in a nice car. I have volume and base at permanent 100%. Audio quality is just fine, no 'hiss'. Not used the phone / mic. Not used the SD card. As a means to listen to Spotify in any car with a radio, it just does the job. A carry pouch would be useful (I use an old sunglasses bag) as you can't leave it permanently 'on show' in the car as some idiot will put the window through for it. You can buy these for much cheaper, but I'm glad I paid a bit more for this (£23). Good product.

### ⭐⭐⭐⭐ You can choose which folder or playlist. Most of the others don't have this feature which is a must.
*by S***Y on 2 June 2025*

Excellent, I'm happy with everything so far. Only had it for a few days now. Things to improve is to have more gap between the USB and charging slot because if the USB stick is not slim you'll struggle to get them in at the same time. Most important thing for me is that you can choose which folder to play. It would help if there was a button to forward the songs on the playlist. Performance wise I'm happy.
