I have a ~6-year-old Clevo laptop (from Mythlogic, which tells you something). After about five years, the keyboard kinda crapped out. Got a new keyboard, took about ten minutes to swap it in. The hard part was getting the part, had to order it from China.
I have one from mid-2014 (base model W550SU, now-bankrupt distributor), used about as heavily as anyone would ever use one (probably averaging sixty hours a week). Its keyboard was not great within one year (spongy), and distinctly unpleasant after two years (very spongy), with its space bar becoming extremely unreliable during the third year. It became impossible to type at speed on it.
