This works really well and was straight forward and easy to connect to phone. Bearing in mind that it's not a Bang & Olufsen system, the sound is good during a conversation even when driving on a noisy road surface, and the person you're talking to can hear you clearly. Maybe you could spend more money on something ' fancier' but I honestly can't see why you'd need to.

Not disappointed
First off, it feels a bit plasticky cheap, but, I suppose it is cheap so that's what you get. From an operational point of view, it's not bad. Immediately found and paired with my Sony phone and connects automatically when I get in the car, assuming I've left the device on. Call sound quality is better than I thought it would be for this price, it can be very loud, too loud in my opinion but at least it can be turned down. Google asisstant appears to work OK which is a benefit for hands free sending texts and making calls etc. You can play mp3 through it from a device but I wouldn't recommend it, the speaker/amp isn't up to music, for calls yes, music, no. Overall, a halfway decent device for answering your phone and texting etc whilst driving, not disappointed in the purchase at this price.

Does the job
I've been using this unit now for around 6 weeks. The battery lasted around 5 weeks from a full charge, connected to 2 phones simultaneously for around an average of 6-7 hours per week (with satnav directions running through it) and an average of 30 mins to 1 hour phone calls per week. Not bad going really and better than I had expected. The auto on/off works very well too. Only slight negative is it plays a low battery message when it runs down to 10% battery, which although a good idea it does get a bit annoying that it repeats itself every few minutes. Sounds quality is more than adequate, slightly 'tinny' sometimes when at a louder volume but most of the time perfectly fine. If your car has a fairly quiet drive or you mostly spend time driving at 50mph or less you'll be fine. It's only slightly tinny sounding when I have it turned up loud and that's only needed when I'm driving at 60mph+ and because my car isn't very sound proof! 99% of the time the person on the other end can hear me clearly and the 1% times they can't it's usually poor signal on my mobile which is no fault of the unit. I debated whether to get a Bluetooth unit that played through the car stereo but glad I didn't. I listen to music through the stereo and this unit plays my phone satnav directions. Overall I'm happy with the purchase; does the job well and at a decent price point.

Crystal clear communication at a bargain cost
Having purchased this for my work van, this is worth its weight in gold. Initial start up was straightforward and had connected automatically almost immediately upon opening the box and switching on. Profit arrived with enough charge and has not yet required a charge up. Sound charity is perfect and volume is very loud for a 2w speaker. Easy to use 1 touch button / control knob that activates the Google assistant and voice control to dial up means that I know longer have to pull over to make phone calls saving valuable time during travelling. A great product at a fraction of the cost of bigger brands in the market, I would definitely recommend and will be buying more of these for the rest of my small fleet of vans in the business. The only disadvantage is they there is no display with caller ID but with the phone mounted to the dash, this is not a problem. Overall, if you need a means of reliable contact with the outside world then make this product your must by item!

Great buy!
Very pleased with product. Easy to install and connect to mobile. The clip for the sun visor is somewhat wider than expected so to avoid it falling on my lap I don't really put the sun visor down. The sound quality is good and you can choose to have its speakers or your mobile speakers. Pity it does not connect to the actual vehicles speakers (my car radio is not Bluetooth enabled). The motion sensor is absolutely spot on and makes life a bit easier. It will actually tell you it's connected. All in all a great buy.

Just not good enough - here's why....
It's small, fits on the visor nicely, easy to pair with two phones. The sound quality is good, very basic functionality, so value for money is ok. it reads out the sat nav well. the music quality wasnt great, plus you just have your music blaring at you in your face as it is inches away on the sun visor rather than quality sound from your speakers. However, you have to remember to switch it off whenever you leave the car otherwise your phones dont disconnect from it, eg. you finish your journey and rush in to the office/home, you wont hear the phone calls coming in as the sound will be ringing in your car not your pocket even if set to vibrate. This also means you have to remember to switch it on every time you get in the car. This also means that depending on its mood, you may have to re-pair, or select it as a device on both your phones to connect with it, everytime you get in the car. It does do this automatically some times. I have both a work and personal phone to do this with every time. Its tedious. The bluetooth is temperamental and connects/disconnects when it wants to... it randomly says Power Off for no reason when you are driving. Sometimes it disconnects your bluetooth all together, so by law you would have to pull over and choose the device you want your phone to pair with again. Its just hassle that you dont need when you are driving.... there are other bluetooth hands free devices out there that apparently recognise when you have left the car, so disconnect or power off automatically. Although the sound quality was good, i would just rather have an FM transmitter one.... I should also say, i was driving, the sun suddenly hit my eyes, i was blinded and pushed the sun visor forward with the device attached, and it flew off and hit my dashboard. I had to react quickly to the sudden burst of sunlight and i dont think it is great that it comes off so easily if moving the sun visor. Its a good idea, its just not fit for purpose really

Finally a winner!
I consider myself an expert on Bluetooth visor speakers. I’ve owned 4 over the years. I decided not to cheap out thus time and went for one over 50 bucks. Let me begin by saying that you get what you pay for. Pros: - Excellent battery life. I last charged this unit over two weeks ago and it’s still showing 90% - Great sound for 2 watts. No complaints. - easy to operate. I send voice texts with this unit and have no problems. Very easy and seamless pairing. Bluetooth pairing with 2 phones is also seamless and I have not experienced my phones dropping out of Bluetooth like I have with others. Peace of mind. Fast pairing as well. No waiting and voice prompt notifies you when phones are paired. All in all an excellent speaker. Cons: The clip could fit tighter on the visor. The placement of clip on one side of the speaker allows the other side of the unit to dip down on bumpy roads. I think the placement of clip is to allow you to replace lithium battery after they’ve run their life out. Would have been better to affix the clip to the battery door. - Pairing light is very dim. Can’t see it during the day too well. That being said... I am a night driver and it’s nice that the light is not flashing brightly which can be distracting. M nit picking. That’s it!! I would definitely suggest this speaker unit to friends and family.

A mediocre speaker not worth your time or money
This little car speaker is fabulous! I tried 2 others before this one (including the Motorola sonic rider) and had to return both. The CK11 connects automatically most of the time, and if not, an easy push of the main button connects instantly, even when a call is coming in. I’ve used it for 3 weeks on a single charge! Speaker quality is good (not great) considering the price point. No issues, definitely recommend Feb 2020 update... Not working well at all. Bluetooth connection is spotty at best, sound is distorted at high volume. A frustrating waste of time and money. I gave up using it and now use my iPhone on speaker while it’s on a vent phone mount - works much better than this product!
