It works very well with my iPhone. It si is much better for me to write a longer message by it than to use my oversized thumbs. Also, I have some problem with just a 3-year battery life. However, the best design for the collapsible keyboard was my old "Universal Wireless Keyboard by palmOne". If ever someone would make or copy the same design with the Bluetooth compatibility, please, let me know. I would replace it with any other collapsible keyboard anytime. It was light, a very smart design, the right size of keys and batteries were replaceable.
