Exterior

It's hard, not plush or squeezable, but the material feels super smooth and pleasant to touch. Barely oily at all. Not something you'd need to powder. Simple shape.

It's semi-transparent, so you can see your cock going in and out, and if you hold it under a strong light, you can also see the textures inside, which I found hot. However it's still semi-opaque, so fine details aren't visible. In particular, I wasn't able to see my cum shooting out inside it, which is a bit disappointing as that was what I was really hoping for. Maybe I just need to get better lighting or to save up for a bigger burst, lol.

Interior

The opening ~33% has a bunch of nubs, which is my favorite part, it's super stimulating around my glans. The rest of it, especially the middle third, pretty much feels indistinguishable to me.

Which is unfortunate, because holding it under a light and feeling the inside, the middle has these sort of fins/folds, and barnacles and ridges and flaps. Like many toys, it looks so alluring and feels amazing with my finger, only to turn into an ambiguous blob when my dick goes in. However, that opening 33% is super distinguishable and feels great.

You need to be rock hard to enjoy this. Think about that: it means that if you're not particularly in the mood to start, it won't really work. Makes it hard to use this for e.g. a relaxation session if you're stressed out from tough times. Whereas other toys, you can start using it when you're semi-hard, and build up the erection in the process, ultimately enjoying and relieving yourself regardless of how you'd been feeling before.

It'll also push itself off your dick if you don't hold it down, especially if there's air inside it.

It's got very intense suction, and really, really holds onto my cock's head when I pull out, in a way other toys don't. But I actually prefer to have air inside the toy when thrusting, it seems to make the sensation of the opening third of the toy better.

Scent

Basically no scent at all, it's very faint.

Sound

It's loud and lewd.

What I like most is when you thrust all the way in, and the air inside the toy is forced to evacuate past your dick, out through the opening. It makes a super loud squelching sound, and the first time it happened it even spurted lube out onto my balls.

So yeah, if you need something discreet sound-wise this might not be it. But if you don't, I thought the sounds and flow of lube were lewd and arousing. Kind of like someone gagging when giving a sloppy blowjob/deepthroat.

Durability

Out of the box, there were a couple small internal air bubbles near the opening. It's not something that concerns me (no effect on usage, doubt it'll matter for durability) and it looks kinda cool.

In general this is a harder toy and should be super durable. No issues from usage so far. I don't expect to have any, certainly not for a long time.

Overall

First time I used it, I came harder than I'd cum in a long time, and it was one of my favorite toys.

However, as I've tried more stuff, I've come to realize that I prefer softer materials, and prefer longer, slower sessions. Of the harder toys I have, this is my favorite and I'm glad to have it as an option, but I don't think I'll reach for this regularly.

Oh yeah and the box art is hot af, monstergirl fans unite
