We must consider the thing with the price: 11 Euros for less, the set is complete and does its job. After almost a year of use, everything works like new. Yes ... as the first day ... That is with a keyboard still relatively noisy, but the keys that do not have high hardness and are pleasant to practice. I think for my part that the gap of the keys is curiously large enough, can reduce typing speed sometimes ... We find all the standard keys, without thinking about the "Read", "Pause" ... other keyboards. Finally for the mouse, it is optical with a long wire as the keyboard, 3 button without extravagances.
