Personal experience is not good.
First of all, the overall design of the laptop is relatively compact, the heat dissipation is worse than that of the desktop computer, if you pad a keyboard pad, it will significantly affect the heat dissipation, long-term use not only affects the performance, but may cause the laptop to crash or damage parts.
Secondly, the keyboard pad affects the feel of typing, the pressure of the original keyboard is obvious, the probability of error is low, and the pad is easy to press not in place after the pad, and the wrong play occurs.
If you do not have a cooling pad, in the absence of playing the game, you do not need to pad something else, heat is normal. If you often play games, it is recommended that you buy a cooling pad, which helps the heat dissipation of the notebook and can also assist in cooling.
