What is there to know?
I’m all in for functional upgrades.
I’ve learned a bunch by being here and there is always so much more to learn. The community is great and supportive.

I’m in central KS and I’d be willing to help anyone that needs access to a Proxmark 3 RDV4, I’ve got the DT ProxLF antenna if that’s something you’d need for peace of mind on a t5577 write.
