I got a saxophone that played really well, but it had a couple of ugly cracks on the lacquer so I returned it for a new one. They did send me a new one that didn't have the cracks, but had problems playing from C to D (and it wasn't because of the octave key, which was working properly). The keys were also noisy. I think this is a matter of luck, you can either get an instrument that plays well or get something in between, that's why I would rate it as "inconsistent". I would recommend you to save more money and go for a better sax like a Yamaha YTS280 or a Jupiter JTS500 that will probably not have these inconsistencies.
Further comments:
-The instrument is really beautiful (especially when it doesn't have any cracks on the horn) ;)
-It's heavy.
-The keys can be really noisy.
-The pads are not of good quality. (but we can't expect Pisoni pads at this price range)
Despite all of that, the first time I got a Sax that played really well...So if you are lucky you can get a very good sax.
