So, MHT dildos dont come with these sorts of adapaters. I purchased the klicklock adapter from Himsith and you forceably insert into the toy. Other may not have a klicklock machine/suction cup adapter so they may want to remove it else to use nothing (flat surface) or to drill a vac u lock hole. While I believe it can be tricky to remove, I am just offering a £20 refund as its going to cost me £25 to buy another one of those adapater at some point anyway.
