I missed out on this deal when it was posted for £9 some months ago and had it in my basket waiting for a price drop. It has dropped in price even further today after it was between £20 and £24.99 for some time. Seems a very well rated product and a comment in the previous post highlights that for some unknown reason you will want one.

Link for a previous deal/comments and price history in first post. Product details:
