Edit: The company responded quickly with great customer service and replaced my Bluetooth FM transmitter quickly with a working device.

Original:
After many attempts, it did not pair with my iPhone 8. I will return and buy a different brand.

Trying to love this unit again..finally got the Blue tooth to hook up with my phone so I can listen to music. The 2 outside speakers don't work. I tried all settings in the surround mode. Nada.. this may have been the problem all along. Sounds like crap. I'm going to contact them and see what's up.
 They were helpful the first time I called.

Bought one for my husband as a Christmas gift and despite it working initially out of the box then charging it up, it failed-- no Bluetooth connection, no sound- zippo. An e mail to contact the seller on Amazon got me in touch with Jennifer who asked that I take the speaker and send it back in their box with a prepaid label once I received another one from them with a free carrying case. The replacement speaker is working fine and has been charged twice and has no problems connecting to Bluetooth or sound issues.

I read several reviews on tech websites and was convinced enough to give this a try, despite other negative amazon reviews.  The 1st item I received did not sync with my phone using the protag app (despite the fact that I have the current version of Android). The bluetooth control panel showed that phone could sense the duet but without it syncing to the protag app, it was non-functional.  I returned it and got a replacement...which did the same thing.  I emailed the manufacturer asking for advice and received a prompt reply asking for more information.  I provided the information and have not heard anything back, 1 week later. There is NO troubleshooting or technical information included in the packaging with the duet and there does not appear to be any additional information or support posted anywhere online either.  I'm returning both non-functional items and I'll just to to remember where I put my keys...

I had trouble getting them to work, then once the bluetooth connected it would do what i expected. So, I put them away. I tried it again 3 weeks later and couldn't get the bluetooth to connect at all.

Bluetooth just stopped working.  I contacted them and they told me how to reset, but that only worked once.  I tried the plug in but that did not work either.  A very expensive mistake.

This is an updated review.  I originally rated this item one star, as the Bluetooth quit working a few weeks after I got it and I had gotten no response from Soundfreaq.  However, a couple of days after my original review, Soundfreaq reached out to me about the problem.  They agreed that it was a hardware issue that was covered under warranty.  They immediately issued me a RMA and a free return shipping label, so that I could send back the defective unit.  Today, I received a brand-new replacement unit.  I thought it was admirable that they sent me a new speaker, not just a refurbished speaker.  As a result of the great customer service, I have modified my review.  Thank you Soundfreaq.

Original review: I received the Soundfreaq Pocket Kick as a gift, and I really liked it at first.  It doesn't play as loudly as I would have liked, but it was adequate.  Unfortunately, 2 months after I got it, the Bluetooth stopped working and I could no longer get it to connect to devices, rendering it completely useless.  I contacted the manufacturer through their website for help, but they never responded.  I am left with a useless, speaker shaped brick.

I did everything Logitech said on there Web Site to get the Item to work, but it never would. Blue Tooth wouldn't connect at all. So after 30 minutes of trying everything, I uninstalled the Software and the Item from my Phone. So it's back to using Google Maps.

I received it on time thanks to Amazon two day shipping. I opened the package and put everything at charge for 2 hours. I was able to turn on and pair the Bluetooth earpiece but I was unable to turn on (therefore pairing) the headphones. I saw a red light while charging which turned into blue. I pressed the multifunction button to turn it on, nothing happened. I pressed and held the same button for at least 5 seconds and nothing happened. I did the same thing while on charge and still nothing happened. I am thinking that I got a bad one and will return it. But I may give it a try one more time with a replacement hoping for the best.

I purchased this for use with a set of Bluetooth headphones.  The transmitter successfully paired with the headphones and all was good for about 3 or 4 hours.  The pairing/connection was then lost and could not be restored.  The device was returned.

UPDATE August 18, 2015:  The day after I posted the brief review shown above, I was contacted by a representative of Tao Tronics with an apology and an offer of a free replacement so that I could give their product another try (I had returned the original to Amazon and received a full refund).  The replacement was received within a few days and I immediately placed it into use.  I have used the new device extensively and it has worked well.  I will note that the manual indicates the device should provide about 10 hours of operation on a full charge.  The first time I used it, I got about 3 1/2 hours of usage until the charge was fully depleted.  Since then, it has not been an issue for me since I simply leave the device plugged in.

In summary, I would now give this transmitter a 4 star rating.  The company stood behind their product and the replacement they provided satisfies my requirements very well.  I'm withholding the 5th star since I have not experienced close to 10 hours of operation on a charge.

The device looks perfect but the Bluetooth doesn't work. Very annoying...
