To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought this product to run in my business. I immediately bought a SmartNet contract (Cisco) through CDW. When it expired a year later Cisco refused to renew it because the seller was not a Cisco authorized reseller (even though I had already purchased on SmartNet contract). They call products like this "greyware" and refuse to back them - at all. If you buy it you are on your own - Cisco is horrible to work with.
Purchased a brand new product that should have a 1 year warranty through Cisco. Unfortunately this was not the case. The firewall died 4 days after Amazon return policy, contacted Cisco and the 1 year warranty expired in late October. Paitenly waiting for someone to resolve this.
