Bought this for my kid, but have played it myself to some extent. Two main problems: 1) Does not hold tuning very well, needs to be tuned often. 2) Intonation is a bit off, meaning that I can't seem to adjust it properly, and two of the saddles are at the end of their range.
When set up and tuned, it works. Passable as an instrument (as opposed to a toy), with real electronics and OK sound. In all quite impressive for the price.
