10 votes are a little bit. By 2 channel 2 way system with 3 Watt per output sound to my ears but 6 votes it really good, especially with Hall effect.
The vibrato effect is somewhat exaggerated and therefore for me unusable.
Power supply is only simulated and not available (ie only 4xAA battery operation possible), no headphone output, which is particularly disturbing my neighbors! :-)
Recording only about 45 seconds at a time. (Low capacity)
No electronic fault in melody + 3-tone chords found !! So 4 to 5 keys in parallel without sound error !!
One-finger chords unfortunately possible only in conjunction with a rhythm. (Volume is not controlled separately).
For a very low price you definitely get here for strumming useful Keyboard .....
