Color: Black Style: 48W
I've had other bluetooth devices for my car and this is the best. Very easy to install - just plug it into the lighter recepticle - and pairing it with my phone was easy. It doesn't take up a lot of room or get in the way of the cupholder. The usb ports also charge my phone well; I've found that others charge really slowly or even drainig some battery life. Sound is very clear, and I like the changing lights! ... show more

    • Great item
Color: Black Style: 48W
Perfect. It has a strong FM signal. It auto connects to my phone Bluetooth when I start the car. It also allows you to talk on the phone through Bluetooth and you hear on your car speaker. It also has a great sound quality.

    • Hands-free even if it's the 90s
Color: Black Style: 48W
Pretty cool. Straight forward plug and play. The lights sync to your music playing. Can take calls via this thing. The sound isnt bad, if you click the button on the bottom and select b01 it makes the bass sound richer. Only complain is that it isnt as loud as you connecting directly to aux but you'd that. Overall it's a pretty useful device if you don't have an aux jack in your car. Oh it has 2 charging ports too. ... show more

    • Great Bluetooth solution!
Color: Black Style: 48W
One of the best purchases we have made. We have an older car without bluetooth. We didn’t want to replace the cars stereo as it is tied into all the cars chimes and warnings. This was the perfect solution. Plugged it in, paired it and it played my music playlist perfectly! Highly recommended!

    • For older cars, this is a wonderful way to add blue tooth connectivity.
Color: Silver Style: 48W
This stupid thing. Seriously. Who needs one of these in 202X? Well, if you have an older car that you couldn't justify upgrading the stereo in, than you do . . . I bought this for an old Saab, and particularly bought this model because it sits more flush than the goose-neck models. My car is a stick, and this is completely out of the way and perfectly sits where I need it. There are a couple things I don't love. One, the lights always default to on. They're easy enough to turn off, but that's the first thing I do every time I plug it in, or start the car: double click the bottom button and disable the LED light show. I know some people may like it, but I find it annoying. The other issue is it can be a little tricky to figure out how to set it up. I've had other models that were a breeze to change the tuning station, but this is a little more finicky and hard to do on the road if you need to. So, for local drives, this is 100% set it and forget it (just double click to turn of the LED each time it starts up), but for longer road trips where you're reaching for the dial to stop station bleed, it's a little more of a pain. Still, nothing I would fault this unit for. It does what it does and in a very small footprint. Sound quality is excellent, especially if you use Radio-Locator.com and the unused station option. On a road trip this is a one-stop-shop for location aware finding of unused channels and a drive from Seattle to LA usually only needs three to four adjustments. Find the right channel (we've always been able to) and it's crystal clear, zero static, and works perfectly. Sure, it's not as easy as having a blue tooth connection to your car's radio, but this is also an item that can be had for a fraction of the price of a stereo upgrade (especially considering installation, any power or wiring changes needed, etc, etc, etc) and it just works, period. If you're looking and wondering if this thing is what you need to be streaming music to your older car's stereo . . . I can say, without a doubt, you'll be happy. ... show more

The button does not allow me to put the volume up anymore, can lower it, move to the left/right but not up. Charges quick if using USB-C but not the other ones. Connectivity is not bad sometimes it randomly disconnects but when connected is pretty loud

    • Great, except the volume.
Color: Black Style: 48W
Generally good. Very easy to set up. The chargers work and I like that it has both USB and USB-C ports, which is why I chose it. It connects and disconnects very quickly. However, the volume is lower than other models I’ve used in the past, and that matters to me. You only have to set it up once, but the volume issue is persistent. Probably good that I can blare my music on full blast, but I sure would like to. :-) ... show more
