The product is well built and relatively easy to set up. Links well via Wifi and Bluetooth. The only issue I have is the lack of availability of the cord to connect the hi res walkman the UK. Sound quality is really good for such a small box

4 stars is pretty generous. First and for most i am disappointed that there is no case available for this speaker. I want to use it when I go climbing and a protective case like what the Bose has would be a great accessory to keep the speaker safe. 2nd is the battery. 12 hours sound good but when using the speaker daily it constantly needs recharging. This would be a bigger issue if using more than 1 speaker, linked throughout different rooms. This couldn't be a permanent setup, a 1 night party maybe. 3rd, the fact that the speaker cannot be used while connected to an AC outlet. This would allow more regular use at home. HD sound is good however.

Bought this based on in-store reviews and am not disappointed. Connects to every device without any problem and streams at superb quality and volume (if you want it!)
