Summary: Great sound for its size. Very portable! I am disappointed with the battery life. An estimate of 5 hours play time was advertised, but I have only been able to reach 2 to 3 hours of play time at a moderate volume. I would still choose this speaker regardless of battery life.
Great relative to price and size, but there are better sounding alternatives

Summary: After reading a bunch of reviews on Amazon and other places, I bought this one, the Bose® SoundLink® Bluetooth Mobile Speaker II - Nylon and the Ultimate Ears BOOM Wireless Bluetooth Speaker - Black (980-000678) for a little sound bake-off. First off - the Flip lost immediately. If you want something small, light, and inexpensive and aren't as concerned about sound - then you can't do better than it.
Summary: I returned mine and bought a Logitech UE instead. The Flip sound's a little better and is built like a tank but that is about the only thing I liked about it. The AC adapter is huge, almost as big as the speakers. Not convenient for travel when the Logitech, like many others, charges with Micro-usb. Bluetooth pairing is hassle with multiple devices while the Logitech quickly and easily paired with everything.
Summary: The speaker produces sound quality far better than you would expect from a speaker many times its size. However, the need to press and hold the power button every time you want to sync up with a device defeats the purpose of having portable unit like this. I have other bluetooth speakers that do not require this step, so it is not a technology limitation. Likewise, the battery is advertised 5 hours, but lasts maybe 4 at best...and the charging cord unsightly and bulky.
Summary: The unit works well on a windows and iPhone but would not pair with my Samsung S4. The sound was good, not great but good. There was better sound then some units costing much more. However it pales in comparison to the JBL Charge Portable Wireless Bluetooth Speaker (Grey) . The Charge costs 50% more (100 vs 150). The charge is bigger (around 10-15%)... about the size of one of the larger energy drink cans... But the sound is significantly better.
Summary: Cnet rated this as the best bluetooth speaker and the Amazon reviews were very good, so my expectations were pretty high. The Good: 1. I like the sleek design. It's easily transportable and the travel sleeve is great. 2. It sounds very good considering the small size. It has good bass and I don't notice any distortion at higher volume settings The Bad: 1. Bluetooth cuts out for a second on average once every 4 minutes.
