This is the Uniden BTS200 Bluetooth speakerphone, which retails at $59. I bought it cause I wanted to cheap, portable speaker to connect to my iPad to stream radio into my son's room. In addition to it's Bluetooth capability it also has a line in and a USB out from it's 2950mAh rechargeable battery, which allows you to charge a mobile device as well as run the speaker.
The speaker quality itself is what you would expect from a $59 device, however it is loud and doesn't seem to distort. You can easily use it in almost any size room or in the backyard. I used it in a conference room for a team meeting last week and the sound filled the room nicely. The real strength of the device from my use so far though has been the battery life.
Officially it is rated for up to 7 hours usage and in the manual it states it will last 5 hours at 80% volume. I just came back from a trip to Busselton, 4 hours driving total, with this streaming music for the whole drive (car stereo sucks). Despite this, the LED battery indicators show that it still has over 75% left.
I haven't, and don't intend to, use this device as a speakerphone for calls so I can't comment on it's performance in that regards. However, I'd recommend this to anyone looking for a cheap, portable and decent sounding speaker to stream music to.
