It's a Bluetooth keyboard with good-sized keys that are raised and have the kind of action which lets you know you've actually pressed the CAPS Lock and it's designed to be paired with tablets and even smartphones to give you an authentic typing experience. Best of all, it actually folds down into a tiny slim form which can easily be tucked away into your bag or case.

The design is genius - it even includes a fold-out stand - but the standout feature has to be the dual-pairing. Once you're using a full size Bluetooth keyboard it doesn't make much sense to be still typing on a phone with your digits.

So just connect both phone and tablet to the keyboard and swap instantly between the two. Perfect for when you want to write one of those lengthy essays people are fond of on Facebook or reply quickly and easily on Gchat.
