Pros: I have used these for awhile. The multi color leds mix with each other and is the perfect eye catcher. Customers love these because its well as pretty as the stars in the sky. These almost double my original sales prices because they are in such high demand.
Summary: If you need a quick fix to cool your case and don't want to spend a lot of money on name brand fancy fans and add a little flash, these are a good choice. I wouldn't fret if these break because their very low cost for a budget.
Pros: These blow air, cool the case and have pretty little lights. They do what they do. - Dime a dozen
Cons: None, other than I wish I could control them.
Summary: Colours don't spin like in the photo, just LEDs in each corner of the fan. Still love em! Since you have to sure a little force installing, I suggest planning out how to thread the wires before screwing in. If not, it's not a big deal to redo, but will take an extra minute or two.
Pros: Very quiet, Colorful, Easy to Install, Cheap.
Cons: Had to use a little force to set screws in plastic frame.
