Never used but don't know where original packaging is.  I put fresh batteries in to make sure it fires up,  it did. Dongle is in its spot.  Gave it a good wipe down, as it's waterproof, and spill proof, plus it just feels good using it.  Like that silicone front and the triple cushion in the back,  really nice keyboards from this company. Set up for Microsoft Windows.  Thanks for checking it out! 🦞✌️🦞
