Review on Enhanced Typing Experience: Logitech MK235 Wireless Keyboard and Mouse Combo by Adam Shuler

I have had this product less than three months and cannot use it. When I try to type at normal speed, the keyboard fails. It either freezes or only writes about half of the sentence and stops completely. It also inserts too many characters like "sssstop" when I press "s" just once, and sometimes there are a few seconds between each character, requiring me to take a deep breath and type in slow motion if I use it at all would like. These problems gradually increased and didn't appear as badly in the first month, otherwise I would have returned it immediately. The mouse is fine.
