Query: Works well even if switched off

I like to sit on the carpet and work and the laptop would get extremely hot because the fans were blocked when kept on the Carpet. This cooler works perfectly well. Even if I leave it switched off it acts as a good platform and the aluminum top helps with the cooling.Pros:Relatively quiet, the high speed is a little noisier, but for sustained use the low speed is fine. Its not as portable as some others but its solid and light and fits in my backpack.Cons:The only way to switch it off is to pull the USB plug out. Also the indicator light is quite bright. The fan keeps running and draining power even if the laptop is on sleep (maybe this is an issue with my laptop)
