We have purchased the recorder to secure digital cassettes. This task is performed, the recorder perfectly beautiful that's the Audacity software is included. I had this SW indeed already, but with other products you will only refer to the Internet to download. Not all users comfortable, and that's really good solved here. The Operating Instructions are printed very small, but still legible and reasonably understandable. I had no trouble installing and and at the first use. For the price you can not expect a mechanical marvel, the processing is OK, but as the lid for the cassette compartment is very fragile, or the battery compartment. Well, that one does not need batteries, but can operate the recorder via USB. General note for those interested. Copying happens in real time, ie a C90 side needs 45 minutes to convert. Since the Audacity software and the device are not linked, you have time to manually stop recording, otherwise the unit records up to nothing then a corresponding post of MP means 3 Files. My tip when sitting at the computer, and something else makes, simply use the time in parallel and copy a cassette. A kitchen timer is to end was a supportive tool for the recording in sync. Conclusion: good price / performance ratio and absolutely useful device to some old tapes to secure digital.
