If you are heavy handed buy few cheap logitech [compact one for laptops ] one of them is 10 year+er guarantee , mine is 12 year old and only "S" is warned out
"I'd read that mechanical keyboards are meant to live for ~10 years." I've a cheap circa 2011/12 Logitech M series wireless backlit board (mostly these days just used for scripting stuff whilst in bed) so that's an affirm. Damn thing's practically bulletproof - spilt coffee, sat/trod on it etc. ....who'd thunk it ¯\_(ツ)_/¯
