This is my 3rd usb lamp, the first two had blisters that roasting slowly until they died and that one is perfect, it's been a few weeks that I have and when I use it regularly, no bulbs have blown again, and it shines very well the PC area. The only downside is that the hose is too flexible, with heat (or even without) it twists too easily and then depending on how the lamp positioning the tomb looks alone, so you have to play around with it tape holds well or somewhat flexible, but it's still a good deal price / quality at this price since what is required of a USB lamp is to properly operate and illuminate and this is the case ! I bought two of the time ... and I think I have time for this time !!!
