I have an original Brydge keyboard (non trackpad) for my iPad Pro 11” and it wasn’t a bad keyboard, if a little heavy. I decided to opt for a Magic Keyboard when they were released and I think its fantastic.
If the Brydge gets a firmware update to bring the trackpad nearer the standard of the Magic Keyboard then I reckon it’ll be a good buy, and certainly an alternate contender fo both the Magic and Logitech keyboards.
