CUSTOMER FEEDBACK
What customers are saying.
I don’t usually write reviews, but this one deserves a standing ovation (if I could still stand after using it!). This thrusting dildo vibrator has completely raised the bar — the combination of deep, rhythmic thrusting and intense vibration is chef’s kiss.The multiple speeds and patterns let you customize every experience, and the build quality feels luxurious and powerful. It’s like it somehow knows exactly what you need. Cleanup is easy, battery life is great, and it’s surprisingly quiet, which is a huge plus.If you're on the fence — hop off and treat yourself. You will not regret it. 12/10 would recommend to a friend... or three.

Love this! Was surprised by the power. Stronger than others I’ve tried. I really like that you can attach the stand/suction cup when needed!

Suctions to most flat surfaces and has many different speeds. It was easy to put together and figure out. Stays charged pretty long.
Sarah04/12/2025
This item is definitely worth it. It comes with a charge, lube, the item itself 🍆, a suction stand with a threaded screw to screw on to the stan. Within minutes I was a mess. It’s hyper-realistic, soft, and you’ll definitely have a good time with it. If you’re looking for something quick to place an old toy definitely get this one! It’s girth and measurements with definitely make sure you’re pleasure. The packaging is cute and comes with a concealed bag for your goodies!
