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.

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.

Hands free gadget
Better sound quality than I expected. Nice we gadget. I have given this item a 4 star because of its design to sit ontop of your visor, but when I do that the visor won't go up, so I located the clip at the bottom but with vibration it falls off, so I've had to improvise using a strip of rubber for packing, so far so good. A clip on the side would be better.

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!

The Best I've Ever Had
I have brought several bluetooth hands free kits, all have been rubbish and some were more expensive than this one! After reading the positive reviews I tried this one and I can't fault it. It has a brilliant feature in that it turns on automatically when you open the car door, it then connects to both my home and business mobile phones. The battery life is weeks... even using it every day. I love the proper volume button which makes using it very easy if you need to. The call sound quality and the connection stability are the best I have ever had on any similar device. This represents some brilliant value for money too. Don't buy cheap, buy this one and you will not be disappointed. I would 100% recommend this hands free kit.

Really impressed
I brought this as my VW Tiguan didn't have Bluetooth, was intending to upgrade the whole system. But this product is fantastic. Very clear speaker and I'm told clear reception. Dad it two weeks and still not had to charge it . The auto shutdown and start up works everytime. And the most impressive thing is the multi function button that activates Google assistant so hands free calls and maps . I'm that impressed I won't be changing my media player in the car now and will stick with this . 10/10 from me 👍

Nice fit on car visor
Difficulty in getting connection to my phone every time. Have to keep in on charge in the car as it dies. Am disappointed as it is quite simple and neat I just wish it worked better

Good piece of kit.
I’m impressed with the clarity and volume of mobile phone calls in comparison to other makes I have tried. It might be me, but I have found the battery life a little short in comparison to their makes I have tried, hence 4 stars. To be fair, the trade off for a slightly shorter battery life versus great connectivity and sound quality is acceptable. I would recommend this item if you have an older car and need hands free, or if you need additional connectivity for a second phone because your primary phone connects to your vehicle media system.

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!
