"As Seen On TV" garden gadgets tested, and they're not great

I'd call it a spoiler, but you already know what's coming: "As Seen On TV" garden gadgets are not much good, however ingenious they seem to be. Household Hacker picked up a few items and subjected them to tests. None were terrible or dangerous, but the gimmicks don't really work - a trimmer that uses cheap zip-ties works OK, for example, but the ties are eaten so quickly that it's a false economy and a great example of the Vimes theory of boots.
