How is mystic like?

Hello lovely people!
I've been thinking a lot lately about getting a new cool toy, and I had mystic in mind. How do you guys think about it? How does it feel especially for anal use? What is the texture like, can the spirals be uncomfortable? I ask because on my small flint, the ripples really hinder me to do any fast thrusts.
What's your general experience with it?
Thanks in advance and have a lovely start into the week
