Just purchased one for in store pickup - lots of mixed reviews, but that is at the original 99.99 price. I figure for 49.99 this must be a great deal.
I purchased a couple Auvio units in December, and while they are nothing amazing as far as sound quality - they get the job done. My bro just bought the Bose Soundlink II (or whatever it is called), but I cannot justify spending $300 on something I'll be take to the beach etc - plus, that thing is relatively heavy.
This may be a good option for those looking for a light, portable, rechargeable bluetooth speaker.
