They are Holy Pandas from the original molds & you really can tell no difference between these (cleaned of factory lube) & the OG HPs, but MD still managed to screw the pooch with these. Terrible factory lubing that basically renders the switches unuseable out of the box. IME some have ridiculous amounts of lube in them, then other seem to not have been lubed at all!? I really feel sorry for those who ordered these & threw them straight into a hotswap board.
Although after they are cleaned of the factory lube & properly lubed with a quality product they're the real deal. I'm typing on them right now & while I don't have board full of OG HPs to do a true side by side comparison I do have a board built with Satanic Pandas (Holy Red Pandas) to compare it with. They both feel great & give huge tactility using Halo stems, but the MD HPs seem to have a bit more bite to them & remind me more of the OG HPs I got to try at meetups than the Satanic Pandas do. So I'd say it really comes down to how much work you want to do just to have the Invyr housings. With MD's pricing on the HPs now, it'll cost you right around the same amount to buy a batch of YOK or GSUS & Halo switches to make your own. Also don't forget about V2 Zealios, sure they don't have the signature HP bottom out sound & the bump feels a little different, but they have even larger tactility & are super smooth compared to any HP or HP variant.
