    Not a huge fan of the mouse scroll but overall a very good keyboard and mouse combo.

    But the set could use a different combo with a different mouse like the MX series. 720 is not perfect.

    Very challenging when no clear instructions are included. I have trouble with the keyboard and mouse staying paired with my desktop. Also the letter “e” occasionally does not work. Tried to get help from tech support but that didn’t work out. Not happy
