We bought this piano for our son who is eager to learn a lot of instruments. We at the same time as it being a gamble (on him being willing to continue playing) wanted a good product with a long potential and flexible life, so not only things like 88 weighted keys, dual 1/4" plug outputs and mobility (no integrated stand) were important. We like that it is reasonably light, can sit on a keyboard X-type stand, and has a strong focus on grand piano sounds. The other sounds are considerably more cheesy, but that's OK, it's a piano! We run it with Garage Band in an iPhone and some PC-based DAW/Sequencers too. This works flawlessly. Quality-wise, the keys feel OK, and there have been no problems with the hardware.
What we could not get but wanted are:
XLR outputs (yeah, one can dream...)
Internal power supply with IEC connector
