Review: Initially I received a faulty product. Item was replaced fast and I was happy. Good price & product. - Edit: Company was A++. They sent me a replacement super fast. So far the replacement is trucking along just fine. The one I originally bought that went completely dead must’ve been a one-off manufacturing defect. Hey, it happens to the best of companies. Battery life is much better this time around on my replacement device, sound quality is good-superb just like before. No pops or static or anything. Very clean. Range is excellent as well. Sometimes I’ll forget to disconnect my phone when I stop somewhere and get out with it to go into a store to pay for gas or something and I’ll come back into the car and the podcast/music will still be playing. As in it never lost the signal at an estimated 50-80ft plus range. Just my everyday use review. Not sure on its max range. It’s a good product for its price. And if there’s an issue customer service is prompt and dedicated. —————————————————————— Sound quality was good. Battery life was meh. It would last I estimated 3-4 hours max before it needed to recharge. But I only had it just over a week of light use and it just wouldn’t turn on again one time. It died and went kaput. Spend your money on something else that’ll last you more than a week or two.
Review: Highly recommended! - I bought this for my 2012 Harley because it still has the original head unit. It works perfectly! It is extremely easy to install and use. I love it because it leaves the port on my phone open so it can be charged at the same time. The cord is a great length for me because it allows me to place the Bluetooth piece in my windshield bag. The charge lasts much longer than expected. There’s no issue with sound quality or disconnection from my phone. Highly recommend for the money!

### ⭐⭐⭐⭐⭐ Good device
*by M***Y on 21 March 2021*

Pretty good device for the price. Easy to install, and came with double sided adhesive to install on the dash. You have the choice of plugging in the aux connection directly into the device or use a cable to be able to move put the device anywhere. The aux cable as well as the charging cable are nice and long. I strapped them up with a zip-tie to avoid dangling cable. My cellphone connects automatically to it when holding the button for a few seconds. Press once to mute or twice to call the last recent number. Sound quality is good during calls. Only downside is see at the moment. Phone call volume is all the way up, but I have to crank up the radio to hear. Once the call is done and the music comes back up, it is crazy loud and I quickly have to turn it back down.
