I was recently in the market for a Filco Majestouch Minila keyboard. I was very scared off by a few reviews which said that bluetooth just stopped working after a while. Is $500 worth it if it could break after a year? Maybe if it was under warranty. Anyway I opted for the wired version.
Never mind my Logitech MX Master 2 mouse which I could never get to work using Bluetooth, and even disconnected all the time with the USB receiver.
