Vibrant geisha balls, it's original! They measure 20.5 centimeters long (9 centimeters insertable for both balls) and 3.4 centimeters in diameter.
After cleaning, reloading, and lubricated, they slip into me. Then just press the button at the end of the cord.
Unfortunately, I do not find them more different than a vibrating egg, I do not find the same feelings of Geisha balls certainly because of their light weight (65 grams) and I find them a little noisy.
That said, the toy is nice and easy to use.
Conclusion
These Geisha balls are positioned on two very different sectors. Vibrating eggs, and Kegel balls. But without really being able to stand out. They are less effective than standard geisha balls, but offer interesting internal stimulation as a vibrating egg.
I recommend this purchase if you want a sextoy in addition to good clitoral stimulation, or to spice cuddles before penetration. But if you are looking for geisha balls for their main use, I advise you to go on a model like this one or this one without engine.
