DELL I personally use this brand, is easy to use and since three years I never find any fault to it. It runs near about 14 hours per day, but I have not find any problem to it. Whatever the quality is not much value has been kept for it. My best friend also use the same and He found a problem after five years of perching and service provider took just 24 hour to salve it. I wll say this brand is the Best.
