Great idea flimsy construction excellent software
Starting with caveats first:
1) The cassette door's hinge is on the short side. Laws of physics would tell you - it's easier to break it. Handle with extra care.
2) The player has no speakers.
3) The battery compartment opening is inside the unit (which is very unusual). It is difficult to open since the main door doesn't open too much to leave space for you to pull the battery door. So if you have a big hand you may crack the main door's hinge. Again be very careful.
4) The output power is less than usual. It doesn't play loud at all. This would make sense when you're transferring tape to computer (high volume = distortion) but it may not be so good for typical listening.
The good:
1) This unit could be USB powered. Wow!
2) The unit has USB output to computer for audio capturing.
3) The software included support both Windows and MacOSX
Tip:
Due to the low power output the audio capture must be amplified. One easy tool is Audacity. Typically you need to amplify it to N minus 2 decibel (e.g. if Audacity's amplify option suggests 11db you enter 9; if it suggests 6 you enter 4) then choose bass boost option (use Audacity's default). 95% of the time the results would be very loud playback capability with great mid-bass and bass without distortion.
