Need a wireless mouse and keyboard combo and decide to try a Dell OEM set. DP/N 0XF89J.
The set is manufactured by Logitech and uses their unifying receiver. Logitech is quitting OEM mouse market so you will see fewer and fewer Dell mouses made by Logitech.
The quality of mouse is significantly better than the wireless mouse that came with my HP ENVY 750se desktop. The HP mouse (and keyboard) are made by Anatel.
