At first it didn't work, but after contacting support they gave me a new one in less than 10 minutes

funzionante, tempo di attesa 10 secondi per l'nvio

Chiave arrivata immediatamente dopo l'acquisto e perfettamente funzionante!

Wowww thid really works, at first I thought it was a scam because I bought windows home rather professional so it didn't want to accept my code becouse Im instal windows 10 pro ... it was my mistake btw I bought the right one a while ago and entered the code without any problems, any recommendations satisfied

Buenísima experiencia funcionó de inmediato y muy barato además, excelente servicio.
