Many people, including the author, sometimes use the iPad as a small notebook, tweet, chat on QQ, and even write articles. So the author has been looking for a suitable keyboard protective shell, which can not only protect the screen, but also become a keyboard. Logitech has launched relevant products for the iPad series before, and now the iPad mini is also available. Logitech's Ultrathin Keyboard mini is very similar to the original iPad version, which is made of aluminum alloy. You may be worried that it will be heavy, but the original Ultrathin Keyboard has been widely praised and is one of the best accessories in the same category. The keyboard includes USB charging port and Bluetooth start button. Usually, like Smart Cover, you can connect the iPad mini with a magnet, pull it out and put it in the middle to start typing. Although the battery is half less than the iPad version, it can also be used for three months. The Ultrahin Keyboard mini will be first launched in the United States this month at a price of $80.
