What is the duration of Netgear Armour Subscription against purchase of new Orbi router (For India)

Netgear has set up a community forum specifically for the Armor product. Most of the people who watch that forum are more likely to have experience with Armor and know how to work it better than those of us who follow this forum. Might be more likely to find someone who has a solution if the question is posted there:

Thank you. 

The referenced web site indicates that customers can activate a 30 day trial of Bitdefender Armor.

After the free trial, customers may purchase a 1 year subscription for $99.99US (this comes up when clicking on Complete Feature List.) Payment and activation is handled through the Orbi app.

It might be worth spending a little time looking at the posts in the armor community forum to see what customers are saying about the product.  (Once I saw "Free Trial" and $99.99/year, I lost interest and have never activated it.)  Many of the posts that I encounter are from customers frustrated at Armor interfering with their activities or pestering them with reports about "vulnerabilities" that they have no possibility of addressing (television sets in particular).

The Orbi router, like all routers, includes a firewall that rejects connections from the internet unless the user has specifically forwarded ports to devices on the LAN. And most devices on the LAN also include firewalls that do the same.

Good Luck.
