I asked him twice before purchasing if Dark Aether was working on the tool and he said yes. Anyone using tools knows that DA is a bit broken right now and only a few tools can successfully give the full camo so I made sure to ask about that specific feature since that's what I was after. He said it was working so I went ahead and purchased 1 month. Was a bit dumb on my part for purchasing 1 month, but I figured there wouldn't be any issues since he is a Trusted Seller.

First thing I noticed when opening the tool was that even the login page was laggy. I ignore it. I hop in a game to do dark aether and it's working for all weapons except the 2 that a bunch of other tools are having issues with. I try multiple different methods, none work. I try giving myself weapons, it doesn't work because the tool is constantly try to open something in the background so it interrupts anything I'm trying to do. I sent him a 7 second clip (linked below) showing that in those 7 seconds alone the tool bugged out twice on me. This is a constant thing too, it isn't something that happens here and there.

I messaged him about it and he asks if my "processor is the bare minimum for cod." Although there is a small chance it could be that, it's highly doubtful considering I've used multiple tools and this one is the only one I have issues with.
I bring up the DA not working and he says "tools don't work that way" and that it's a "user error." Which as I mentioned above, A LOT of tools are having issues with DA not working properly.
Seems to me like he's just trying to deflect from the fact that the tool isn't working the way it should.
