Need a UK TKL wireless keyboard for 3 devices, can't find a good one

Maybe the Logitech G915 TKL. I got it as a gift for my birthday and I absolutely love it. It works with Windows as well as Mac and can pair with up to 5 devices. It comes with a wireless reciever so you can use that as well as the bluetooth setting. You can choose between different Layouts on the Logitech website. It has amazing battery life with up to 40 hours. It is super thin and has addressable RGB that sincronizes with your current setup. I hope I could convince you.
