I decided to bring a keyboard, however it is a little bigger than an iPad and cannot be used for travel. has benefits The sound is almost inaudible, the keys are soft and smooth, and switching between devices is easy. Since the iPad program does not function, the system itself changes the keys, and it appears that this cannot be adjusted. Cons: Some keys on the iPad do not function because of their small size, but this problem will eventually go away. Opening the battery compartment is inconvenient because there is a chance of shattering the plastic.
