    Tenía problemas de cobertura desde el router hasta el cuarto donde tengo el ordenador, con un montón de paredes de por medio. Y ahora he ganado bastante de señal. Os recomiendo la compra.

        5 estrellas si señores me a encantado comprar en esta web.
        Envio Ulta Rapido, vivo en canarias y muchas son las veces que se me quitan las ganas de comprar cuando pienzo en los tramites y tiempo para recivir mi pedido. Aqui solo 4 dias, muy muy bien esto es seriedad.
        La antena es una marabilla de antenita, producto auténtico y buen acabado, enmel Rango de los 5Ghz es una pasada la tasa de trasferencia.
        Gracias nos volveremos a encontrar en bebé.

          Queria comentar que el envio fue muy muy rapido acostumbrando al vivir en Canarias a tener que espera muchísimo quede muy contento, solo tardo 4 dias y la antena es una maravillosa antenita. En kaly linux me tira de cojones y en w10 abro los videos de YouTube al istante pero al istante istante.
          Gracia y comprare mas cosas próximamente.
