I am using this product from last 20 days and I am completely satisfied. It works very good with Win-7 setup. First step is to install the software (provided in CD) and connect your R-W-Y wire to input cable provided. Just plug in to USB and start the application. PRO: Almost plug and play. Clarity is good Sound is good. Window re-sizing is possible CONS: Sound goes off when you restart the application. It require to select a option (sound option in setting) and need restart of application. This happen every time, when you restart the application. Overall, very good devise and useful as well.
