Review: Great sound quality with simple application - Have an older car that isn’t equipped with all of the new fancy technology. I ordered this Avantree CK11 and it is working for my needs perfectly. Once I charged it and paired it to my phone, I had immediate connectivity. The volume is nice and loud easy to hear and the calls have great quality to understand. It pairs well with my iPhone and Siri. I can even have Siri read my text that I can hear over the speaker and reply if necessary to my text without touching the phone. When necessary I charge it overnight and it’s ready the next morning. I charged it in January. It’s now April and it is still fully charged.It connects to my phone as soon as I open the door and get into my driver seat. It’s a handy little device for hands-free cell phone while driving. Connecting and disconnecting with calls is one button function. I’m very satisfied with my purchase. I wish I had done this sooner.
Review: Great product for the price and excellent customer service - We bought two of these units for our older cars whose bluetooth software was too old to pair to our newer phones. Setup was easy on the first product, and the sound quality is very good for this price product. In fact, the sound quality is better than my (supposedly preimium) car speakers as far as spoken word is concered. We had issues with the second unit, and I emailed customer support on July 3rd. I didn't expect to hear back from them because of the upcoming holiday but got a response within a couple of hours. I had some dialogue with them which continued on the 4th, and the customer service rep Sara offered to set up a phone conference. In the meantime, I did get the unit to work properly. I switch back and forth from listening to books on my phone and making and receiving calls, and everything works very well. One really nice thing about this unit is you can set it to power on when it detects motion, and it will automatically power off after 70 minutes with no activity. It takes a little getting used to in order to properly interact between phone (I have an iphone) and unit, but it is sweet in the end!

### ⭐⭐⭐⭐ NO LONGER The bane of my automotive existence... :)
*by B***O on May 30, 2019*

UPDATED 7/31- My original review skewered this device (see below). However, Avantree has been good to work with and willingly replaced what appears to have been a defective device. The replacement no longer suffers from the audio dropouts, and the good qualities (loud, multipoint connections, and volume knob) are still good. I do still occasionally experience a disconnect or two when connected to devices that were rock solid on my now-failing Moto Roadster, and hence I'm upping to 4 stars rather than 5. Ultimately, it's a fair bargain for the price, and it impacts me far less since I've gotten a newer car in the interim (and scaled the older one and this speakerphone) down to my son. He uses it and has reported no issues. ORIGINAL REVIEW BELOW (n/a on replacement device so far) I've held off because I really hate writing negative reviews, but I can hold it in no longer. It's entirely possible that I just have a bad individual unit, but I have seldom been so frustrated at a gadget as I have with this one. I bought it to replace an aging Moto Roadster 2 whose battery is starting to become a problem. My intended use case is for the odd en-route conference call but more often for on the road podcast listening in my older car. The Moto has served admirably in that role for years. First the good... The speaker is plenty loud & great for podcast & audiobook listening. It pairs with two devices simultaneously. I like the volume adjustment mechanism. The battery life has been great. Now the problem... None of the above matters if the device doesn't work consistently. No matter what device(s) I have connected, it will randomly disconnect/connect while in use. More frustrating is that while streaming audio, it will simply go silent. It doesn't disconnect and stop then but rather keeps "playing" on the source device. This means that I miss chunks of audio. Sometimes stopping audio on the source and starting again fixes it temporarily. Sometimes I have to dis-/reconnect. Sometimes power cycling works. The one consistent behavior is that it ALWAYS does this on every trip now independent of the source (have tried Galaxy S10 and s10+, iPhone 8, Galaxy Note 9, and LG V35). I lose calls, can't stream audio consistently, and end out endangering lives messing with it. I've resorted to just using the phone's speaker at max volume. I've reset the device entirely and repaired the devices. Nothing fixes it. I considered chucking it out the window, but I need to see if warranty service is possible. The results of that effort will determine whether or not I revise this review. For now, but at your own risk.
