All worked as described. Like one or two others I was slightly sceptical but was encouraged by the honest sounding descriptions on the screen ie. it'll only work on one installation. I followed instructions carefully and it has all worked perfectly well so far. Many thanks.

Worked perfectly, no problem

Le voy comprando 2 veces y pude activar por teléfono, todo perfecto

PERFECT!!!! Receive the key instantly and worked just fine. Thanks!

Bought 10 keys for different systems over the course of two years.
The keys continue to work and activation is always successful. (with the exception of one key that did not work, which was quickly replaced by the customer support)
