Hey highoeyazmuhudee, thanks for the video, I was also wondering about these different movements. In my case the 2813 makes an audible whirr when I move my hand too quickly, does the same happen with the 4813? Or the ETAs for that matter... Perhaps it's a lack of lubricant?
Either way, thanks for the video
(And as my first post here, hello everyone, great forum you have here. Hope I can contribute at some point, but for now I learn )
