In the past, some fake Zeal V1 switches had been sold on KBDFans.
It's my understanding that, in order to continue having a business relationship with ZealPC, KBDFans had to break ties with the manufacturer who sold the fake Zealio V1 and other fake Zeal switches.
Are you sure about there having been fake tactile Zealio V1?
Zeal V1 came up in the discussion about the fakes, as well.
I actually had received some "Zealio V1 R11" switches from KBDFans. And by that time, people were wondering how Zealio V1 R11 was still being sold, months and months after KBDFans received a limited shipment of them. It was as if they had received a truly enormous shipment that lasted a long time, despite demand.
So there was speculation about the Zealio V1 R11 being an unusually long release, even before the fake Tealios were spotted.
I don't remember what people said about Zealio at that time, but I believe photos were circulated of how to spot a fake Zealio from a real one. There were differences in the molds, particularly the housing and legs.
Some people also reported the Zealios feeling different than before. I found mine to be unusually soft and weak.
KBDFans refunded me for my Zealios. Some people had assembled the late "R11" Zealios from KBDFans into builds, and experienced failures with the switches. So maybe they really were counterfeit.
Later on, we would see Everglide Jade switches, which some people say use stems that appear to be Zealio V1. I'm not sure about that, but they are real nice switches when modded. I guess more manufacturers need to be "inspired" by Zealio V1!
