I can type on calls without my mic picking it up, it has a custom layout saved on device so I don't need to do any configuration for any device I connect it to and it works fine on Windows, MacOS and iOS devices.
I use a JP version but with US keys on it and a US key layout which gives me a bunch of extra keys to configure. If anyone is wondering, there is a spare key on the home row to the right of the ' key which I use as backspace/del.
It wasn't cheap, but if it broke I would replace it with the same model in a heartbeat. I do have a spare but it's the standard US layout with the big spacebar.
