This review is actually for two of the same kind of laptop cooler, mine and my daughter's. They worked great for a couple months, but then the fan blades on both of the coolers started getting stuck on the inside of their enclosures and breaking off (mine now has 3 blades on one side and 5 blades on the other).My daughter's cooler started to have a problem with the power cord on the end that goes into the cooler itself, and it needs to be jiggled and moved around to find a position in which it will work, and then held in place. Then it stops working again and needs to be jiggled and moved to another position and held in place again.Both of these laptop coolers (my daughter's and mine) are now much louder than they used to be, and they vibrate more, probably from being off balance due to the missing fan blades.My advice is to spend the money to get a better quality laptop cooler that won't break after two months.
