Wanted something convenient to listen to music in my bathroom while getting ready for the day. I'm pleasantly surprised at the volume and the range of sound it puts out. Sounds great. Battery appears ample, but it's got a plug-in. Buggy with my MacBook Air (Mountain Lion) with Bluetooth connect. MacBook REALLY doesn't like it when both it and my iPhone are connected at the same time. Hard to get it reconnected. Disappointed about that, seems like it should offer more of a seamless transition between both products.
