Las teclas son mecánicas, las famosas y las mejores, las Cherry MX blue (color azul), que son muy ruidosas pero son las más cómodas y que menos cansan para la escritura y mucho trabajo de teclado. Je dirais que pour le prix, cest pas trop mal, mais je déconseille pour le studio. Plenty of room but the straps are too tight and they dont adjust. AFter getting the racks installed they do look nice but. The best way to get the straps right is to leave the straps slightly loose. In the last year I?ve had additional foot pain develop and realized I need a slipper that gives me all around support of my foot. Mouse works great. My top 2 features are the durability to withstand a child that is a little rough and being wireless! Very nice headphones I would buy again, using on 2 very different PCs one very basic for work, other more advanced for gaming, the work PC ran just fine on first try with Logitechs G Hub software. Item appears very sturdy and well-made but I was disappointed to find that the only easily collapsible part appears to be the top rail which collapses down to meet the joining section of the two legs although my husband says it may be possible to part-dismantle the legs after each use.
