I've sourced a collapsible spare wheel for my Q5 and now need a jack. The standard Audi jacks are commonly called widow makers because they are considered by many to be inherently unstable and unsafe, the design resembling half a scissor jack. Has anyone acquired an alternative, perhaps a scissor jack? The disadvantage will be that it's unlikely to fit the foam cutout in the boot, but I'd prefer to have a jack I can have some confidence in.

Edit: I may have this wrong. Can anyone with a  later Q5 please confirm whether the jack is a scissor jack, or the type that opens to a V shape, resembling half a scissor jack (this is the one known as the widow maker). I have seen both types advertised but have a feeling the later model came with a proper scissor jack/ Any help appreciated.
