I really like the buttons. I have two of the 6-button versions, two of the 4-button versions, and one 2-button version. These work reliably with the drivers by @markus and are responsive.
None of the mesh issues that the old Aqara devices had: these buttons are Zigbee 3.0 devices.
If you don't mind the long wait for delivery, they're available directly from Aqara:
