Feature:
This product did not include features, and it was not on sale. It's features that are the most impressive are the simplicity of use. It is not rocket science, it produces the most common sounds, piano, e piano, harpsicord, organ, and strings. These can be combined, and the reverb and brilliance settings are great. I can also record-without a manual!!!

Quality:
I have not taken it on the road, but I cannot foresee a problem. This is not a top of the line product, however, for the calibre, the quality is very good. I was impressed by the keys themselves, the felt above the keys, weight of keys, size of keys-ease of use.

Value:
In comparison, all things considered, for a portable digital piano, I think for both home, recording and occasional concert use, this instrument is perfect for me

Desirability:
"sex appeal", this is a digital piano-this question is n/a in this case.

Sound:
The sound is very good for the price. I have yet to hear it live, but judging from the what I have heard-plugged into a PA or a board for recording could only enhance what is already very good

Support:
I have just purchased this instrument, and in time will be able to accurately answer this question if need be

Overall:
As Roland is a good name, with a good reputation, this portable is a welcome sight for me. I tried another non portable and found the sound to be close to the same...time will tell.
