Rui Carmo updates his long-term review of the Logitech Combo Touch for the iPad Pro M1, noting that while the keyboard and trackpad have performed excellently over four years, he faced issues with deformation of speaker slots which raises concerns about its durability. Carmo recently purchased a new Combo Touch in 'Oxford grey' as Logitech does not sell covers separately, and he hopes this one will last longer without similar problems.
