Feature:
This item came with a drum key for tuning the head. It does not include the stand. It could have a higher quality, external speaker for playing without a headphone. Only the metronome can be heard through the external speaker. The headphone sounds are great and allows for adjustable volumes and click sounds, practice speeds (30-200) and a variety of time signatures to practice to. You can set the pad timing to grade you less precise or more precisely, at a variety of measures. The Accuracy Score, Quiet control and Stroke balance are features I liked most for improving timing and dragging/rushing problems. It doesn't matter how good your technique is, no one will want you in their band if you can't keep good time. Quiet Control- Especially helpful with note accuracy, tests your ability to stay in time while click disappears and reappears, much like when working a fill or a stop in a live setting. Auto/UpDown- conditioning your timing from fast to slow and back in a controlled exercises to click. Stroke Balance: Measure the exactitude of your R, and L stroke for balanced sound when striking the drum- a very important element in producing a clean roll on the snare.

Quality:
The quality seems good. It is not made as sturdy as mesh drum triggers that Roland uses with the V-Drums, but it is built sturdy enough to meet its purpose. I wouldn't travel without a gig bag for it.

Value:
In terms of value, this product worth its typical selling price compared to other items. The reason I'd pay more for RMP5 instead of RMP3 is because the RMP5 allows you to add Roland external triggers for a Hi-Hats, Bass drum, and Cymbals. It is a bit pricey, but its worth the price ---with the RMP5 you have the starting block from which you can build a low-cost, awesome-sounding, electronic drum kit for quiet, in-home practicing/or midi controller for recording basic drum sounds.

Desirability:
It's a sleek design, and feels great to play.

Sound:
The sound are much better than drums sounds in some lower priced electronic drum kits. the pads are very responsive. You can actually adjust the responsiveness to your liking. You can also adjust the head tension to resemble that of an acoustic head or tighten it up to feel like a traditional practice pad.

Ease of Use:
Manual is a must, the interface is pretty intuitive once you've walked through the functions. It really helps to simultaneously follow along with manual, as you learn to how to use it. The learning curve is fast, but it's really easy after a once through with the manual.

Support:
I have not dealt with Roland before except when playing a synth. My impression of years in music is that Roland is a great company who takes pride in their products.

Overall:
I think it would continue to serve as a useful training tool for a long time provided that Roland continues making replacement heads. If I bought one, I know I'd add the external triggers and make a little practice set for at home. Go to Roland to see a great video of one of their techs playing this practice kit set up. I like the interface and the sensitivity trigger pad, and the factory sound samples. It's lightweight and easy to use and overall a fun little machine.
