The head came with a slightly erased eyebrow, but I think they can be painted on, also the layer of silicone covering the lips in the corners is a little torn, this does not affect the appearance and you can only notice it if you open your mouth wide. I have a soft silicone head with ROS from Irontech and it's the same thing, so this is a common problem. But I think it can be glued with glue for silicone dolls.
Material: silicone is denser on the outside, but still soft and smooth to the touch. Inside, everything is much softer. This contrast creates a pleasant feeling.
Additional features: I ordered the head with heating, sucking and wide throat (max circumference 10.5 cm). Everything works perfectly! The pump sucks in for a few seconds, creating a vacuum, and then releases air, and so on in a circle. There are 3 suction duration modes in total. You can lie down, let go of your hands and enjoy the gentle suction, it is not strong, but still pleasant. Heating begins at the end of the tunnel and gradually spreads throughout the entire oral cavity. This takes about 15-20 minutes. It will be a little cooler at the mouth, but the deeper you dive, the hotter it becomes, this adds to the excitement.
Tunnel: the problem with my previous head from Irontech was a narrow throat, but here the throat is wide enough, like a real girl’s, and the tunnel smoothly goes up. The relief and softness are good, and it is very pleasant to penetrate the entire length of the throat.

I recommend this head specifically with the maximum circumference (10.5 cm) and rate it 9/10. I took one point off the corners of the lips, although there is nothing wrong with that and it does not interfere with either appearance or use. Everything else is done at the highest level, and the sensations are very pleasant. This is real deepthroat!

Head with all additions (except ultra soft lips). Arrived intact except for a small dent on the top of the doll's head, but this is impossible to see with a wig/implants.
All functions are working heating + pump. All devices use Type-C.
The pump adds a new feel, but is a bit noisy for me (although the noise is not surprising for such a small device).
Based on my experience of about 30 onahols (including large ones) - This head is the best attachment in my memory for oral sex.
Even taking into account the fact that this tunnel does not have a transition to the pharynx (as, for example, it is implemented in Magic Face 2) - this head remains in the first position.
The channel is really long and well-developed. There are no problems with the internal diameter either (although I thought it would be tight), but no, everything fits perfectly, nothing is too tight (I chose the maximum circumference - 10.5 cm).
The silicone inside the mouth is quite soft, and the outer silicone of the head is a little harder - this creates a wonderful contrast of sensations along with the soft mouth.
The head skeleton does not interfere with the process in any way.
Cleaning is quite simple - at least for me.
After several times, the silicone feels great, without tears or a hint of tearing. Only the paint peeled off a little from the inside of my lip (but maybe it’s my own fault, due to lack of lubrication)

To sum it up, this is an excellent purchase in all respects, which I do not regret. I hope this head will last a long time, although only time can tell.
ps. I would also like to see an option with hard teeth, and an option with channels in the nose that are connected to the main tunnel.

Thank you for your attention, and I apologize for the possible incorrect translation, I used a translator.
