One really can't desire more for the price. I played on It for a good year now and I Just recently switched to an Aerophone AE-20 fromm Roland, mainly because (and this Is my opinion as Professional musician) I found the responsiveness of the EWI somewhat underwhelming. You can't expect to double tongue or make fast and huge dynamic changes here, but this definitely won't be a problem for beginners or people who aren't at a pro level with their own instrument already.
For just having fun with digital sounds and playing without getting phisically tired, the EWI absolutely does it's job right. It's awfully easy to set up, the tones are good enough (the "real" instrument sounds like flute, sax, oboe... all sound pretty bad if you are used to the real counterparts, but the synth sounds are overall nice to hear and play with) and the fingerings leave room for playing scales on different ways, so that everyone can get used to it pretty easily. The touch sensors can be confusing at first, but you can adjust the responsiveness in order to more easily play the notes clean.
Lastly, the EWI is NOT a practice instrument for saxophonists. Those searching for a digital sax to practice with their Headphones should probably look at the Yamaha YDS-150. It's also not perfect, but anything else just won't really cut it.
For Studio productions with external VSTs, go look at the EWI USB, that's the one for you!
