The pen also works perfectly with my Glalaxy S4, certainly with all other devices.
Alternatively, I also have a Trackball - Logitech mouse, but I use mostly just for my laptop. I also have a Logitech Mini keyboard that works perfectly, but a 2nd part you have still with you.
Only the material quality is the "spine" to want something other, which made however be solved well with black electrical tape (not visually conspicuous, functionally well). Solely because of the pen I would give me the best seat shell at any time buy back (currently six weeks use with transport in all kinds of containers, such as backpack, briefcase, luggage, etc.)
