The Sonic double ended dildo has multiple uses that range from couples play to solo DP. This bad boy is made of silicone which is fabulous for it's intended use. The dildo does have some floppiness to it, but this is to be expected for the intended uses. There are two unique ends with their own design and size, but some might find the girth on the one end a con. Overall, this is one great toy for solo or couples play.
