Let me start by saying I love the way it "finishes" the end of the Provari for my rba's. However, it seems that only a handful of my toppers, specifically the ones with adjustable center pins, work on the stupid thing. My Russian 91 is fine, and my KFL Clone is fine, however the Aspire BDC's (510 connection), Novas, Fogger V2 rba, some misc cartotanks, and my IGO-W RBD will not work on the hippo, PV just reads "OP" when I try to check the atty ohms. I know the center pins aren't making contact but it doesn't seem like I can do anything to make them work with the hippo. I like the hippo's airflow control with the mods that don't work, in case anyone is wondering why I'm trying to use it with smaller clearos and carto tanks. If I remove the hippo and put the topper directly on my Mini, they work fine. I did buy the authentic hippo from vaperev, just not sure why the darn thing only works with like 2 of my toppers
Anyone else have this type of trouble?

Todd
