Can I use both scents at the same time or do I have to pick one?

The 2-in-1 design lets you run one fragrance at a time. You can alternate between Lemon Squash and New Car whenever you want — no waste, just swap based on what you're feeling that day.

How long does each scent last?

Longevity depends on cabin size, ventilation, and how often you're driving. Most drivers notice consistent fragrance for several weeks, but how long it actually lasts is going to be unique to your car and your nose.

Does this come with a hanging mechanism or do I need to grab something else?

It ships ready to hang. Check the package when it arrives — if mounting hardware is included, it'll be in there. If you need an aftermarket hanger or clip, those are sold separately.
