Positive side:=20 It works (stereo playback/recording only, 5.1 sound does not).=20 Cheap (around $17 in Moscow).=20 Has LEDs that blink when data is sent over USB bus. Negative side:=20 You have to find correct recording volume, otherwise all you will get=20 is a cheap guitar overdrive - it seems that 100% rec gain is realy = 200-400% gain over=20 source level. If I set a mixer (Behringer MX) to -10db (level required = by most=20 consumer equipment) and line volume at 100% I'm getting distorted sound under any OS (both 7-CURRENT at home and XP at work). I will not recommend it to anything serious. Yuriy
