I've tried all three textures and I like the wavy (clear) the best. The other two were just not quite right for me.

Wavy is easy to place just right and move up and down a little for great stimulation. It's even better with Wet Platinum lube. https://www.edenfantasys.com/sex-essentials/lubricantssilicone-based/wet-platinum-bodyglide

The others I either couldn't get just right or I'd move it the tiniest bit and all of a sudden I was getting too much or too little stimulation.

I found the nubby one (purple) a little too intense not because the vibrations were too strong, but the bumps were just too hard.

I found the tingly one (blue) the most uncomfortable. The little fingers tend to flick around even with pretty good pressure and can give you that jolt up your spine. That's great if you like that sort of thing, but I'm not a fan.

These have been fun for partner play - they're not intimidating to a male partner as some dildos might be. It's not to replace him - just to enhance the experience. I also love the clear, since it's not too girly - he doesn't mind using it on me. I also love that because it's not that intense, he can play around without any real fear of hurting me. Of course, boys love "more power" a la Home Improvement's Tim Taylor, so I actually like that he can't crank up the intensity and send me into a state of shock. It's a really safe and fun toy.

It's not the most powerful and only has one setting, but it's enough to do the job. I have to say, even having used it dozens of times, I am still surprised by the intensity of the climax I get. Maybe not a "Screaming O" but it's certainly good for a quicky solo or partner play.
