Dude(s), you have no idea how many times I’m climbing up or going down stairs and wishing I could just grappling gun it.
Batpoles come in a close second if they count as a gadget. Bonus: I wouldn’t dislocate my arm and fall to a gruesome death each time I used one. Well, hopefully not.
I would also like the gloves with the spikes. For science, of course.
