Tesco Swansea are now doing this dock for £10.00,
Technical Specs are shown on the tesco site. In store sorry.
I bought one of these a while back, the dock is superb, with treble and bass control its really packs a punch. Also with the video output you can watch i tunes video content on your tv, whilst the quality of the video is reduced its a cost effective way of viewing videos on your tv. Simple remote control, very lightweight and a good handle at the back of the dock makes it easier to carry. Very sleek look as well, comes with the dock adapter so your ipod sits well in the dock.
Fully worth the £25.00 i paid a few months ago, now tenner will be going back for one more as a back up.
