Key didn't work the first time, but I wrote them an email and they replaced it extremely fast.
10/10 customer service, key worked the second time.

Very good price and very very fast.

Il supporto è ottimo . La chiave composta da otto gruppi di numeri è lunghissima da copiare a mano e non si può fare un copia e incolla.
Comuunque il prodotto funziona e sono tempestivi nella risposta. La licenza è a vita ma rimane attiva fino a quando non reinstalli office o fai modifiche significative al tuo hardware PC.
Grazie al supporto tecnico

Instant delivery! Activation without problems - just follow the instructions!

Downloaded the content from official site. No phone activation support in Poland anylonger but the activation site from instructions did the job. No problem, easy process, safe to buy. I had some technical problems with other purchases but support gave me fast and acute answers. Great deal, great seller. From my experience I can say it's a great buy.
