Well made. Sturdy and looks cool. Is a copy of the e-bow
Comes with a 9V battery installed and an additional one
Has 2 operation modes. One with which you can get a normal violin-type of sound and one that produces overtones. Combining both modes in a slow solo is just amazing
Has 2 rails that guides you to place the device in correct spot and start playing
A little bit big, kind of uncomfortable, took me a bit to get comfortable using it
