Ordered afternoon, received the next day at the same hour. The sound is very average but efficiency is formidable: between the time I unpacked and the person he was in office, it is past 30sec. No installation CD, no manual to read: hook, let Windows find the drivers, enjoy!
I use to fill the gap of my microphone jack socket broken, and it's perfect. Obviously the sound quality is worth the price! But when it is simply skype with friends, this is more than enough!
