LawBeefaroni, since these LEDs are on the outside frame of the fan rather than in the center, you'll be able to see the lights whichever way you have 'em facing.
vladgur, do you realize how little current it takes to light up an LED? Trust me, you're not wasting electricity. I'm not sure what you'd consider "annoying" about them. Look at the pics people have posted, and the reviews. You'll see what they look like, isn't much room for interpretation there. Figure out from those if these are something you'd want.
Me, I'm definitely keeping my two. One for an exhaust fan in the back (won't be able to see it until I get a case window), and another as an intake behind my Spider-Man fan grill.
