Notice it says in the description that the base is 22mm. The air hole on the positive pole looks larger too but that may just be because the picture is more up close. I'm tempted but hesitant since i got burned by the 22mm Yiloong clone. I wonder who makes this one?
The person on the other forum that sold me the Yiloong clone sent me a free EhPro Squape R with all
three decks. I'm guessing the decks are extra from the Kingtu because i don't believe EhPro has released the separate decks yet. I haven't had time to build it but i did take it apart and the quality is as expected with EhPro...smooth threading, tight tolerances (but not too tight). I still don't trust whatever the coating is they put on these things but i may build it once just to see what all hype is about before i sell it.
