Vox AP2BS amPlug tiny bass headphone amp review and demo - Is it any good?

Demo of the features and tones from the tiniest bass headphone amp out there. The Vox AP2BS amPlug is much smaller than a cell phone and easily fits in your pocket for travelling anywhere. It has some nice features as a drum machine with a few patterns, adjustable input gain, tone, volume, and an auxiliary input to jam with tunes from a cell phone. But is it any good ?
