I purchased this to use in my 95 Subaru. The radio doesn't work and I wanted a hands free option. This was affordable. It is easy to connect and sounds ok. It can be a bit tinny sounding. But it does its job. I can listen to music from my phone and also make/answer calls while driving. I did have issues with determining how charged it was. I'd turn it on and my phone showed it was at 100%. By the time I get to work it's at 60%. The drive is about 15 minutes. It never died on me though but I'd only use it for 15-20 min increments and it was usually for listening to music. All in all it works well, is simple to use, and sound is good. However I have an old car and it's not as quiet as newer cars so people had a hard time hearing me when I was on a call. I could hear them just fine though.

After a recent law change in our state, we have to go hands free... The ear bud types don't work for me, so I went with this type device. I use it in my work van and chose this model because of the google button. Programming bluetooth was very easy and Google set up in the first try. I had to adjust the clip to make it fit tightly to my sun visor, but stays in place well. I was concerned about the magnet, but it seems to be tight and makes it easy to remove for charging. Battery life seems to be very well, I hope it stays that way. The buttons were a little confusing at first, but work well once I finally read the directions :) Speaker is nice and loud for radio or bluetooth music, but not so loud for phone calls. I have to lean forward to hear when making a call, and the visor isn't that far away. Make certain your windows are up or you may not hear at all. I haven't had any complaints with anyone hearing me or with them hearing background noise when making a call. If volume was improved for phone call, it would be 5 stars. I plan to order a 2nd one for my other vehicle.

I bought two of these to replace the regular bluetooth speaker I had sitting in my cupholder. Installation on my sun visor was easy and freed-up my cupholder, but my husband experienced some difficulties. Since his visor is plastic, the clamp won't stay on, but the speaker is great for the price! Since we bought them to replace our stereos, we're really happy with them. However, feedback from our friends and family regarding the sound quality of the phone feature leads us to rely on speaker phone or just handheld usage. Overall, GREAT product for the price and our intended usage.

When I finally, six weeks later, got it straight and got it to pair with the phone, I was amazed at the fidelity and amplitude of the output. I was amused by the phrase "car stereo" until I put it in the car and started listening to a Youtube channel as I drove. Excellent sound. I am an older person, with not-perfect hearing, so sound equipment rarely impresses me, but this device brought me pleasure because I can hear music and conversation over the sounds of the old pickup and traffic noises.
Sorry, had to take a star off for the instructions, although the apparent (I've only used it for a day) quality of the unit almost makes up for my frustration in getting it to work.

The media could not be loaded. For a tiny inexpensive speaker, this is really fantastic. Putting it on my son's bike so not only can he listen to music, but he can take a call while still riding it. No more excuses for not answering when we call him.

Pros:
LOUD - this is very loud for such a small speaker. The amount of sound that comes out of this is mind boggling. It even sounds GOOD. I would consider this equal to the sound on the Anker Soundcore Flare Mini. It's impressive.
Mic - the built-in mic sounds just as good as the phone itself. When in a call, voices are clear. Of course, in the wind while riding a bike...not so clear. Haha
microSD - Very cool to have the ability to play music directly from the microSD card.
Battery - So far, battery has lasted overnight (not playing music..just forgot to turn it off), and through several bike rides. It's showing at 40% when connected to the phone.
Clip - The magnetic clip that holds the speaker on a sunviser is adequate. It works perfectly inside a car. Also has an optional lanyard to attach to a backpack which is a nice addition.

BUT....

Cons:
Clip - While the clip works great in a car, it is difficult to attach to a bicycle. I came up with my own solution (velcro cable straps) that works fine.

My son is really enjoying this, and so are his friends. It's like when we were kids and would bring a boombox over to listen to Nirvana while playing basketball. Not sure if their parents appreciate it, but that's their problem. Haha
