3 out of 5 eggsok

Pros: doesn't feel like junk in your hand. Music is of ok quality. Battery is fine for what I use it for.

Cons: first one developed a buzz after about a week. Replacement has not developed that issue with over a few months now.

Other Thoughts: The lights on the top are inconsistently lit and the place to press is below the lights which is not intuitive. Battery is ok; you'll get a few hours out of it. The pairing seems to work alright.

Have not succeeded in getting Win 8.1 to use this as primary sound output (although I think that's windows bluetooth issue; I don't have any other bluetooth speakers to compare) No problems with IOS devices.

I have not tested as a speakerphone.

5 out of 5 eggsGreat sound

Pros: Easy to set up
Pairs quickly with my IPhone
Great sound
Elegant look
Small footprint

Cons: There are no cons. I am comparing it to the Jawbone Jambox which doesn't sound nearly as good and completely stopped pairing with my iPhone.

4 out of 5 eggsSuper convenient

Pros: I've had this for a month and I love it. I don't get great cell reception in my apartment so I can take this around and not lose reception. It's also great for playing music on my cell phone and watching content on my laptop without having to use headphones. An efficient device

Cons: Would be great if it had a longer leash in terms of Bluetooth connectivity but still works anywhere in my apt.

1 out of 5 eggsworked 1 day

Pros: light weight

Cons: sound is really not that good (just a bit loader than my galaxy note) and the sound quality if not there

Other Thoughts: i paired fine the first day. However, after pairing my phone to other bluetooth devices, it will no longer pair back with it.

5 out of 5 eggsMy Mobile Office is now complete!!!

Pros: I rarely write reviews unless they're worth writing about and I can honestly say for the price point and usefulness of this product it's worth it. I got this device for use of a speaker phone during many of my meetings so I could talk and type at the same time along with colleagues in the room or outside during my travels. It works fantastic for that and the clarity on the other side it reportedly great. Here's the kicker; once we finalized our meeting I pulled up Pandora and played one of my stations thinking it was going to play on my iPhone. I forgot I was connected to my BluNote and it played on my BluNote and the QUALITY sounded FANTASTIC. Everyone at the table was impressed and wanted to know where I got it and how much it was. They were floored as they paid twice as much for other BlueTooth devices just for music play back. This gives me the best of both worlds and does actually complete my mobile office. This is a must buy at this price.

Cons: Doesn't include a carrying case. Not that you actually need one, but I'd like to product the front of my speaker so it doesn't rip.
