That being said, when I want to head out to the deck or just pack really lightly for a trip, the Seena Foldable keyboard is perfect. It folds down to a very compact package (I included a Magic Trackpad in my photos below for comparison purposes) and it takes up almost no room in my bag.
As far as pairing it up, the instructions in the box worked great and I was up and running in no time. I am very happy with this keyboard and it is exactly what I needed to for taking my iPad out of the house. This thing fits in the front pocket of my sweatpants (as one example), so when I take it out in the backyard, my hands are free to carry the iPad and open doors. Its a great idea and very cool tech! (Below is a picture of it next to a larger keyboard.)
