Same here. I had both Microsoft Sculpt (black, proprietary dongle) and Surface Sculpt (grey, Bluetooth) and ended up replacing them because of wireless issues.

Same here. I had both Microsoft Sculpt (black, proprietary dongle) and Surface Sculpt (grey, Bluetooth) and ended up replacing them because of wireless issues. Currently using a ERGO K860. The Surface Sculpt uses Bluetooth and in my office I'd regularly have the keyboard lagging, like I'd type a word and a few seconds later it would appear. At home it worked fine, but it was unusable in the office. The Sculpt uses a proprietary dongle, which I still use at home, but macOS on my M1 MacBook Pro has a weird issue where it often does not connect. I need to remove and reinsert the keyboard's dongle from the USB-C dongle - removing and reinserting the USB-C dongle from the laptop does not fix it. I have no issues using it on my Linux laptop with USB-C, so it seems to be an Apple bug.
