I absolutely love my Logitech Ultrathin Keyboard Cover.
It’s a clamshell style case. Comes in different colors to nearly exactly match your iPad. It kind of hinges together using a magnet, but it’s secure enough.
The keyboard itself is a great chiclet style, like a MacBook. Works great and holds a charge forever. (months?) Uses bluetooth seamlessly, connecting is a breeze.
Logitech stuff is always great.
The Wirecutter recommended the Logitech Ultrathin Keyboard, but they have recently put their recommendation on hold and expect to crown the Belkin QODE Ultimate Keyboard their newest pick. I have one on order and haven’t used it personally yet, but the reviews for it are all very solid.
