Tried these boys last week in a local Currys... it was £15 back then with a 50% off.
It seems that they just wanna get rid of their stock ASAP, as since then they dropped it even further.
Still some units left remaining. Maybe there's some available near to you.
(I just reserved literally the last in a 25 mile radius)
As of sound quality it is pretty decent. Glorious for £8. This speaker is essentially equivalent to a similar deals from Currys going under the brand of SandStrom.
Collect only, and they seemed to have displayed units that you can try before the purchase.
