I have an HP Pavilion g series laptop and it gets extremely HOT very quickly. I went without a cooling pad for several months and I know it wasn't good for my lap or my laptop. I researched a lot of different cooling pads before settling on this one, mainly because of the price as cooling pads can get fairly expensive. It was a very good investment though because now I no longer fear that my HP laptop will overheat (or it at least no longer burns my legs). This cooling pad has two settings and I always use the highest setting because I feel like the lower setting doesn't do much. It is fairly loud but it doesn't bother me all that much, it's not a deal breaker when I know it's keeping my laptop much cooler. This cooling pad plugs into your USB port so you do lose one of them but that isn't a big deal for me because I rarely ever even need the other USB port. This cooling pad is extremely light and comfortable when it's on your lap. It doesn't interfere with the use of the laptop whatsoever and I would highly recommend it.
