Well, at £2.52 for a memory stick (which you could wipe of its existing content and re-use anyway) it's hardly a major loss, is it?
As others have indicated, you'll get a free video player program which is preloaded with links to websites which show some form of video content. If you really want (for example) to be able to quickly switch from watching the proceedings of the Canadian parliament (in French) to listening to an Indian speech radio station (broadcasting in Hindi) and then onto US religious and shopping channels (before watching sport on Archery TV - yes, it really does exist!), you might have purchased a worthwhile product. Otherwise, simply recycle the memory stick and get the same channels (and possibly a few worthwhile ones as well) for free by searching here:
