Well that's strange, I had the item on ebay up after clicking on the link you posted, it was there so I went to his web address in the item description and was going to advise him, but it said "this item has been removed".
Some have already been sold though and the buyers need to be informed of the danger.
Unsafe products can be reported to the ACCC on
www.productsafety.gov.au via the 'Report an unsafe Product' link.
Cheers Rod.
Being an Ebayer myself, I can't really get involved with the seller.
