Avevo bisogno di sostituire la base della mia serie da ufficio danneggiatasi dopo neanche troppo utilizzo. Mastery Mart si è rivelata un ottimo sostituto, di materiale decisamente più resistente e robusto rispetto alla precedente, sono anche riuscito a recuperare le rotelle della sedia che si adattano perfettamente anche a questa base. Nonostante l'utilizzo intensivo, ritrovandomi a lavorare da remoto, non ho avuto ancora problemi da questa base.
