It's best suited for small offices 10-25 users. Any more and its best to move away to a more higher tier. It will be less appropriate for a mid level company with a large staff. It's best for a small business with a limited budget and less strenuous security functionality.
Great for entry-level networking, and the cost-to-quality ratio is great for the average consumer. I've used them in a crawl space that is not climate controlled, and it just works and provides the switching capabilities I need. These are great for users that don't have a ton of experience and can simply try to troubleshoot with a simple power cycle.
The features are good. The support is good. The resources to deploy, manage, and operate it are good. Customer's feedback and testimonials are good. The updates in terms of zero day vulnerabilities are good and timely. But, I still give an 8 out of 10 because I think the pricing, licensing, and GUI can be improved more.
Cisco's power really stems from its brand reputation and honestly not much else. No one ever got fired for deploying Cisco, and that's why it stands out. The Cisco Small Business RV Series is no exception there; the unit is built well and does the job. However, much more powerful alternatives for routers are out there—the biggest competitor being Ubiquiti. The UniFi routers are significantly more powerful in all regards, including routing speed, IPS/IDS speeds, and VPN functionality. Support for those is admittedly rather lackluster though, so if your network is critical, you are effectively self-insuring your equipment. For some that may be fine, but for others, that risk of extended downtime is just not worth it.
While the Ubiquiti are much easier to manage remotely through their cloud controllers, the Netgear is much more reliable in harsh environments than the other simple switches we use, as they seem less susceptive to high temperatures and humidity. (TP-Link and Zycel are the other major brands we use for simple switches.)
