Summary: I ordered for Christmas 2013. This is a great speaker system. Good battery life, no problems with bluetooth link. It has held up to outdoor use. My only complaint is that it could be louder, but it's not that big of a complaint because the loudness is on par with other speakers in this category.
Excerpt: I bought this speaker to connect to a sunroom TV that has horrible sound from the speakers. The only TV output was the 3.5 mm headphone jack, which plugs right into this unit. I am thrilled with the results, as the sound now is great along with never before heard bass. If you were to use available RCA TV outputs to the 3.5 input on the D100, the sound would be even better, as RCA will produce a higher quality.
Pros: Attractive Design, Easy To Set Up, Flexibility, Good Power Output, Great Sound Quality
Summary: I give this 4 stars because I can't imagine that I'd be happier, or even as satisfied with any other speaker, in this $ range, it uses 4 double a batteries and comes with an adapter, it can be easily connected to non blue tooth devices with cable. Its light weight and looks really cute as well.. Couldn't be happier for "the change''..
Excerpt: This speaker is great, very light and sounds good. I use it in the office listening to ebooks, in the kitchen when cooking or washing dishes, and in our room in cases where i just want to relax to some music in bed (we don't have a stereo in our room). I've never tried it on batteries but there is an opening for 4 AA batteries i think. Considering I had a tinny travel speaker set that ran on the same power, I know this will be better, but how long will it last, not sure.
Pros: Attractive Design, Easy To Set Up, Great Sound Quality
Summary: I am owner of Bose Sounddoc and I have heard the best quality sound but this one is very good given the price. It has limited volume but practically you don't need more volume if you are not in a big party or disco. Also it runs on battery which s very handy outdoors. Bluetooth never fails, pairs automatically.
