日本 Tenga-01 Tetra 旋转软自慰器（透明）

The spiral is indeed interesting. It’s a little tight and the spiral does give a interesting sensation. I will say it’s better than a handjob but definitely not a vagina/deepthroat replacement. What I found great was using it for edge play with a doxy wand and some gentle tugs. Really really takes you to the edge due to the many inner patterns that gives a lot of sensation. The pattern sensation is kinda monotonous so it can get boring if used as a mastubator. Only con is the spiral makes it hard to turn inside out for cleaning and the outer surface can get tacky during use.

it tightens when you pull it up, because of the wire frame - thats why it spins. nice.

Twist and turns inside feels good. Tight suction and can say good way to release. Recommended

Would recommend, easy to clean and fun to play with as a an additional couple.

Kinda gimicky? The twist is nice and all, but since the material is so light, it doesn't get really intense even if you swing it up and down like a drill. Or maybe it's just me. But it has one of the best packaging in terms of both functionality and aesthetics. If you are looking for real-like sensation or even above, look elsewhere.
