Feature:
Everything about this kit is outstanding except for the heads(buy new heads). The hardware that came with mine was top notch, although a little heavy. By the way, the Black Panther snare you get for FREE is an incredible plus. In a lot of ways it's better than the ProM snare that comes with the kit.

Quality:
The ProM series are professional Drums. As I said before, except for the hardware, these are built to the same standards as the high end Orions, right down to the number of holes in the shells for the lugs.

Value:
Best value out there.

Desirability:
I have the Black Chrome Pearl and everytime I see them in my studio I pat myself on the back( I'm sure eventually I'll get calluses). Very proud and everyone who sees them comments on how great they look.

Sound:
These shells sound amazing. My kit's toms are smaller(8",10",12"&14")and I gotta say the 14" tom sounds like a 16". These have similar tones of the Orion series, mainly because they are almost identical to them. Very rich maple shells.

Ease of Use:
Set up properly and tuned accordingly these almost play themselves. Just add talent.

Support:
No need as of 8 months with these, but I can tell you these shells have a lifetime guarantee(try to find that for maple in this price range).

Overall:
I'm confident that these will last a good ten years. The only way I would replace them is if they were stolen or damaged in a fire or something. And yes, I'd buy them again and do plan to get the 16"&18" floor toms on order.
