I bought this bass approx. 2 and a half years ago, I play almost every day at home, never had serious problems with it. I must say that this bass doesn't look as cheap and plays well (after 2 years of actually playing it), it is also very versatile (active, humbucker and pickup, treble, bass, mix + switch for different pickup positions) for every music genre. When I got the professional setup done it was very stable and after the strings wore out, I bought new and the sound was priceless. When you buy a decent amplifier, you won't be disappointed. I like to play more rock and metal stuff in drop tunings and the strings are quite loose and touch the fingerboard while playing (even when you increase the action), the neck pickup has a difficult time 'catching sound' when you tune down below D. Also, if you buy E string in 120 gauge you may experience hard time keeping it in the nut slot (when you tune it down it buzzes) - you either have to file it a bit or just press the string down every once in a while. It sounds good even while slapping or popping.
Pros: price, quality, battery included, sound and versatility (both in playing techniques and music genres), good factory finish and setup, beautiful natural matte wood finish (+ I really like the revolutionary shape of the headstock - so cool, D'Addario strings, tools included, optional bundle with gigbag, very good for beginners, stable tuning pegs, truss rod (good position).
Cons: it is very heavy- at least for me - (approx. 5 kg) - I can't imagine child playing it, and it doesn't have such a good balance on you while you play (I'm not able to play it standing up for more than hour because my shoulder just dies), after your battery's energy level gets lower, you may experience certain buzz or constant beeping when playing in active mode (just change the battery for new one and the buzz is gone), there were certain parts of the bass (knob and screw) that were dismantled when delivered to me, so I had to fix it; the humbucker doesn't sound so good - it's toylike and when you play with a pick it sounds silly.
All in all, excellent bass for god money, worth it!
