The pop at the end is one of the most prominent cervical gimmick I've tried. The first 4 downward "cervical" structures give some decent stimulation too. Overall speaking exceeded my expectations, and the build material seems high quality. I'd say the stimulation besides the end pop feels more mono-tone, but if you're into it like I do then it's so worth it.

The thick rail gives your shaft a good massage. The little bump at the end doesn't do much, but it does give your glans a good stimulation. The horizontal nodule at the very end doesn't seem to do anything. Overall stimulation I'd say medium to slightly lower intensity, but the rail design is still fun to play with. Due to the inner chamber being more spacious, I'd say this toy works best as a stroker.

The material is medium to just slightly softer leaning. The vertical stripes don't grab onto your shaft, nor does it provide much friction/resistance like other vertical stripe designs (Heavens Fall Nine). The end point is not a very typical "cervix" structure where you feel a flap. You can feel a light popping sensation that doesn't stimulate that much, which became what I liked the most about it. Use thin lube if you wanna feel the vertical stripes at all.

The build quality of this toy is there. Decent double layer design with somewhat delicate inner details. The structures are roughly the same as what the pictures indicate. Entrance is quite wide, don't think you'd get good suction outta this toy. The front two segments of the protrusions make you feel like you're squeezing in and splitting a tunnel open wide, but not too much cause this toy is VERY soft. Almost airy and jelly like, no resistance no bounce back plasticity. Maybe I should've went for the hard version.
The end point tooth gives your glans a good tickle and you can feel it standing out, kind of the only standout point of this toy to me by now. Also, don't use thick lube for this toy, use very thin lube to best enjoy more delicate and softer textures!

I want to like this more as I had high hopes for this being the "ultimate answer" to a fun toy with a "cervix" gimmick. But nope, at least not in the way I was expecting.
First off, the "cervical entrance" is not as thick as what's shown in the picture. It's more like a thinner layer of flap, rather than a solid thick layer of "wall" to penetrate. The result is when you reach in, you don't feel much obstruction or stimulation. When you pull out, the flap kind of slaps on your glans and gives a tingling sensation. Comparing to other toys with similar marketing gimmick, it may fit your expectation but I was hoping for more from the thick entrance wall lining.
The dotty texture aren't very stimulating to me at all. They somewhat give a smooth gliding guide to the end, and that's when you use a thicker and very slick lube. Onatsuyu is perfect for this.
The overall material is kinda rough. It feels almost kinda sandy, similar to Time Manipulator's Atelier Onahole. That's very different from the usual very greasy and plastic smell and texture of most other toys. Good thing it doesn't smell or stain with the oil, but sacrificing a smooth material texture.
One last thing, the entrance is quite really small. The tunnel feels close to being tighter than I could bear. If ya thing kinda thick I would say you skip on this. Overall still 4 stars cause I'm a sucker for "cervix" gimmicks.
