Oooh mate, you've got to see one, assemble one and hear one, they didn't put a foot wrong with the Revo top. It's not a small thing so all of the detailing looks appropriate it's not small and messy as it can appear on a pure white product picture. When you see it in context it's very nice, very stealthy and ungodly quiet even for a D5. The bulky isolating mount makes it feel complete, the old ones needed a cover kit before they looked right but these are very good for the price.
The dual top is a bit weird though, it makes every side look like the back. I'd just get two singles every time.
