Feature:
I give it a nine only cause Roland didn't think of adding another floor tom. Other than that, it's really great for people in the dorm or apartment who want all the features of multiple percussion instruments on their kit, while remaining practically silent. By the way, this means no having to run to the nearest music store to pick up a cowbell, tambourine, or foot cabasa; it's all right in front of you with a push of a button.

Quality:
Two words. TOUGH PADS. These pads are tough, as well as the cymbals. I dont think that they will ever wear out; but if they somehow do, I would have most likely gone through three modules to come to a head breaking. That's a feat of engineering. The rack is also amazing.

Value:
Could be a little cheaper, but hey; it's the runner up for the most advanced electronic drumkit on earth. What do you expect?

Desirability:
I play songs that use acoustic drums. That's a job for my miked acoustic kit. But, I want to jam along to other songs with a little 808 or 909 kit setting. That's a job for the TD-12.

Sound:
For an electric kit, this gets the best sound in the world. It's based on its flagship the TD-20 so the quality and detail of the sound is phenominal. But, having recently listen to a live college band with a miked acostic set, it unfortunately isn't abe to produce the high detail sounds of an acoustic, but that shouldn't hold you back. Software such as EZdrummer can get that rich real acoustic sound' while providing that ease of mind that your neighbors aren't calling the cops for disturbing the peace.

Ease of Use:
I only played this for three hours, so I didn't get the whole experience of this kit, but finding the kits, editing them, and saving them as user presets is a very easy task. Thanks Roland.

Support:
I don't own it but they have a great website with support links. They will help.

Overall:
Ok i'm tired of typing so long summary short. If you have an acoustic set and want some electronic sauce to put on the side, don't hesitate; it's gonna be a delicious sandwich to bite into. If you don't like acoustic sets for whatever reason, get it. Some people just want electronics for easy recording, so go for it.
