Feature:
The accessory pouch is nice, and it has a shoulder strap to compliment the handles. It's nice to have both.

Quality:
Quality is very nice. Thy nylon is heavy duty, and the padding is nice and thick. I foresee this lasting a long time. The bag fits the RP500 like a glove. I was worried that, the bag was just a generic one that happened to fit the RP500, but it's more like it was made specifically for it. The only thing I would have liked to see different would have maybe been some slightly heavier duty zippers, but I think these will do fine.

Value:
Other items like this are pushing the $50-$60 range, so this is a great deal. 30 buck is not bad at all.

Desirability:
The bag is very nice, and looks professional. I would have maybe preferred a different color on the piping around the accessory compartment, but it's really not that big of a deal.

Sound:
Well, it's a bag so........

Ease of Use:
Pretty easy, again it's a bag.

Support:
Haven't needed it and I don't think that I will. I will take this opportunity to say, that this is the first item that I have ordered from zzounds.com and they shipped extremely fast. Thanks.

Overall:
I happen to work 24 hour shifts, so I take the RP500 to noodle with in the downtime. The quality of this bag really makes me at ease with transporting it, and not worrying that it will be damaged.
