Very impressive and high quality
Excellent quality and performance. My only opinion is not of Tantaly but of the small derrieres of Asian women. We need more PAAGs (Pretty Assed Asian Girls) in the world.
Did Tantabosom change??
Ok, so I want to start with the positives. This doll is amazing if you’re looking for something on the smaller, lighter side of things. Love the body shape, love where everything is placed. I already own the Diana, and THIS doll is a great similar size, but different experience. Already owning Diana and also an Aurora 2.0, I’m VERY familiar with tantaly’s tantabosom tech. Love it. Which is where my disappointment with this doll lies. There’s no way you can convince me this doll has Tantabosom! After receiving and inspecting the doll, I noticed right away that the breasts were different. I know, it’s a different doll, but the tantabosom feel has been consistent with the previous two doll Ive purchased. The breasts on this doll feel different, they “behave” different. They feel like regular solid breasts on a regular doll. They absolutely don’t have that squishy feeling I’m used too from tantabosom. Which is why I’m wondering if they’ve changed how they make it? Or are they claiming that it has the tantabosom when it actually dosent? Which would be a real problem. I honestly feel because of this it’s a bit If a cheaper product. The Tantabosom feel is why I have no problem dishing out $400-$700 to buy from tantaly. But I swear this doll either dose not have Tantabosom, or they way they’re made has changed. And why I feel a bit swindled paying full price for this expecting the Tantabosom feel, and getting what feels like regular solid breast.

Dear customer, Sorry to hear that you are disappointed with this product. We did not change the production method of Tantabosom technology. You can send a video of slapping your breasts with your hands to our after-sales email service@tantaly.com, and we will help you check the problem of tantabosom not being soft that you mentioned. Best regards, Tantaly Customer Service Team Sophia

Very attractive doll
If you see this doll in person, you will love her. The softness of her body, especially her full breasts and soft buttocks, is something I have never felt before. Two beautiful full breasts protrude from the white skin, and the two firm cherries are delicious. Every squeeze, slap or caress feels real and satisfying.

Perfect replica
As a fan of Ruka Momoto, I was excited to see this store create a beautiful doll that replicates her body. I couldn't wait to buy this product at the first opportunity and I am very satisfied. The quality is amazing—her body is so soft and smooth, and her breasts are well-shaped and equally soft, making her incredibly fun to play with! The size and weight are just right, allowing for easy movement and posing in any position you desire. As someone trying this kind of toy for the first time, I feel like I’ve opened up a whole new world. You definitely won't be disappointed!

Stepped up from Britney
At first I was concerned because I wanted a more lifelike size with legs, but started out with Britney and preferred her rear end shape. Ruka didn't disappoint. While she doesn't have the same apple bottom, the hip shape makes up for it. Speaking of hips, the legs hugging mine provide an added level of realism. I look at these dolls as both therapy and fun, and Ruka is definitely a step up to a more realistic experience. Also good exercise. I believe a Monroe may have been too big a step up and too much hassle to maneuver, clean, and store. Ruka is the perfect size to step up from your entry level torso. I also like the fact that these are torsos, not dolls with female faces. To each their own, but I'm not looking for companionship. I'm looking for sexual growth, exploration, and self enjoyment. A supplement, not a substitute.
