If you enjoy the anal experience you will enjoy this toy. The thrusting and swelling features work and they work well. The only downside I found to this device is that if you choose to sit on the device, the controls that are placed on
the bottom can change the vibration and even turn the device off when they are pressed against a hard surface. So, you get excited using the device and you push it further into your ass and perhaps insert fully and use another surface to keep the device inside of you however, when the buttons get pushed the above mentioned results occasionally happen which causes you to start over. Wish they had put an end on this device that would hold it inside you hands free!
