(sigh) I have an email from sigelei's warranty support stating that they hoped "some or all the issues could be resolved by a firmware update..." 
so it would appear that the confusion that many vendors and reviewers had over the ability to update the device spread to sigelei's support staff.
Mine is now mostly working with a large temperature offset and TFR mode. I don't know about the rest of you but this likely will be my last sigelei.
