This is what they had to say:
"Another coveted piece of hardware available on the website is the Nintendo Wii, a games console released last year that uses a “wand” rather than a traditional control pad for interactive gaming. The console is out of stock at many outlets but you can rent one from £15 a day through Zilok from members in London and Sheffield. The new sell-out Wii Fit software can also be rented from GoodiesRental through Ziloks website for £8 a day.
Zilok lists thousands of items from all over the UK, such as badminton rackets at £5 a day, bar tables at £80, cordless hammer drills at £10 and even a Chinese cook at £60."
