Hank is similar-sorta. It doesn't have the dual-core aspect like the O2 dildos have. If you want the dual-core, the Adam is a good choice that we love. However, the Hank is still a really good dildo, and it's realistic as well. The material isn't quite the same as O2 as it's much more of a matte silicone than the O2 material, but it is still pretty realistic.
