Please review my latest reply. I don't know that your offer for me to have to buy a new and more expensive one solves the problem with the one I have (i did purchase it with the expectation it would work). I also went out of my way to try and help ZWO make it better. I do think there is some consideration needed on your part in replacing the one I have (which apparently you feel as well needs updating). As I said in the email, I don't even know what a new one is like, what improvements were made, etc..
