I purchased the iGo Stowaway Keyboard for use with a Nokia N75 cellphone. Some of the functions on the keyboard obviously won't work with it, but everything that I need it to do works fine. The device has made the N75 much more useful and easy to use. Construction of the Stowaway keyboard seems adequate. I do wish that the keyboard would set a little bit flatter and not bounce some when depressing the keys on the far right of the keyboard. This is just a minor annoyance and is far outweighed by the ease of use with the phone. Overall, I'm very pleased with the product and the feel of the keys when typing.
