lol, I have the same dryer! I hope you're enjoying yours! It's really great for DC-ing, but when you try to rollerset, it's another story.
I use the purple rollers, and it is truly a struggle getting my big head to fit under the hood.
And then once I get the hood on my head without knocking the rollers askew, then drying it is something else. The hot air doesn't really circulate that well, because there's no room. It just comes pumping out of the holes and it concentrates on certain areas and causes some breakage, unless I keep rotating my head.
And then the back never dries that well, so I have to take my head out and let it air dry.
But with the pibbs...
...never again.
It has whirlwind action and the bonnet is so big, so you can fit a whole head of grey and/or purple rollers in there. And it dries evenly, and in so much less time. No rotating of the head...no canceling all my plans for the day to let my hair dry fully...that's like heaven to me. But times are rough...the Pibbs will have to wait.
