Best to just enjoy it for its cover.
Stan Lee's early Marvel stories are more notable for the characters he creates than the plots he puts those characters in. This issue is a prime example of that. It features the first appearance of The Vulture and The Tinkerer, two characters that will become regular Spider-Man foes. The stories however a pretty contrived. Spider-Man beats The Vulture by putting a gadget on him in a deus ex machina moment. It of course operates by magnetism (Stan Lee's concept of magnetism was pretty much 'magic' and he used it in a bunch of stories around this time). In the second story, he just plain gets lucky, thwarting an alien invasion when he punches an alien who stumbles into a control panel which is apparently so flammable that it bursts into flames when you bump into it.
Not really a comic worth reading past the cover which is greater than the comic within.
