I have had them for the past 4 years, these speakers are the best in quality and top notch compared to anything in its category (PC speakers for gaming, music and movies) and its price range! also logitech tech support is SUPERB!
PS- after you get the speakers, never switch off the sub woofer manually from the switch located behind the Sub, even if it is not being used in the night, the fuse tends to blow up, replacement fuse costs like $2, but is a hassle to find as logitech will give you the specs of the fuse, but wont sell them!
