Hi Audax.
I can't find it in my eBay history as it doesn't go back any further than 2014. All I can tell you is it was some years ago when I bought it, and probably not long after I joined the forum. Testimony to the fact it has lasted I guess.
Mine came with a new Saab logo/badge to attach to it, but didn't come with the key blade; I just transferred my existing key into the new casing. The fit of the key was just as firm and secure as the original casing, but not quite as accurately fitted around the curved part as the original, but it has never given me any cause to worry about the electronic bit falling off the key-ring.
I wouldn't say the buttons are 'clicking' ones however - but they are fairly positive, if that makes any sense. At first when it was new, the buttons looked and felt a bit like plastic but are in fact of a much softer rubber-like material.
The eBay seller would have had to have had as near to 100% feedback as possible as I won't buy from ones with poor feedback.
Sorry I can't be of more help.
