No - I didn't end up getting one, but I'm still not sure if that's the right decision.

They are very expensive and the comments gave me pause. I remember someone pointing out that if they had been adequately tested and proved to be that beneficial in a crash, they would be much more visible/highly recommended by say the RACV or doctors etc. Others pointed out that if you wear your seat belt properly, it may not offer any more protection. And then of course, there were views that "yes" it could be beneficial. I hate these types of decisions.

I too looked on ebay and didn't find any.....and you would think they'd be there if people were buying them as they have a very limited useful life for any 1 person.
