I am sorry that you are having issues with your fuchia. Personally I bought one of the 213’s when they first came out and returned it because it would do tc correctly nor do a firmware update as advertised at the beginning. I’ll never buy a Sigele device ever again.
My theorem is working much different on my new device. I was getting burned hits on the 223 in Ss and tcr so sigelei either didn’t improve it or mine was faulty from the start. Once this is sorted out and if I find out the cause I’d like to see the board of the kaos and see what’s changed.
