I was so thrilled to receive a Satisfyer Pro Penguin last month. I got my hands on it at Erofame in Hanover, Germany. I was very curious to see what the Pro Penguin compared after trying the Womanizer W100, the Womanizer Pro and the Satisfyer Pro Plus. These are all suction devices and they work on the principle that the clitoris can be stimulated without the need for actual contact. They have proven to be highly popular around the world and many women report experiencing intense and rapid orgasms with them.
