Do you think the little USB laptop coolers does help?

I bought one of those and I took it right back! It did nothing to stop my computer from overheating and shutting down.

Yes I think they work. My hubby always uses one. Try putting the laptop actually on your lap. It gets pretty hot. I noticed a difference after we started using one.

for me, it can help me and my laptop performance.

For me, every gadget that the techy people invented have its used. In this USB laptop collers case i think it has uses but not that so helpful. Because , first laptop has its own capability of cooling itself. secondly, there are so many air conditioned rooms and comfortable places where you can place your laptop. I think you can apply this laptop collers when you are in egypt . ha ha ha ! Kidding Aside, not all environments you are in can suites a specific product

I think they're only useful if you have nothing else to really place a laptop on and you don't want the thing on your lap. Like, if I had no book or anything lying around, I wouldn't want to put the laptop on top of my bed or my couch where the vents would get covered. Now, if your laptop's fans go out, those would be nice if you NEED to use your laptop and you can't repair them... which if you're spending the time buying the thing, you might as well go get the thing repaired in the first place. Otherwise, I agree, pretty useless.
