Had a little trouble installing because I didn't notice the instructions NOT to install to your storage card. After I reinstalled properly have not had a problem.This little keyboard allows me to take notes at meetings and export them to my computer to clean up later. Beats carrying a notebook and looking for a plug in.The lack of number keys slows you down a little, but the sacrifice is worth it for the reduced size of the keyboard. Great feel, typing is a dream on this keyboard.
