Query: it does wthat it says

this product has been a salvation for my classes. It works just fine. Had to download an upgrade 'cause with my vista notebook it didn't launch. the rest, just fine.An inconvenient it's the size of the files. a 2 hour recording on XHQ it's over 80 MB!!!If you ask me, i would tell you to buy it! :)
