Summary: I really wanted to like this product considering the price point of competing UTM devices. I set this unit up with a very basic configuration - just as a basic router with content filtering and malware detection enabled for a network of 30 PCs. Right out of the box, connected to a laptop for config, unit status showed 100% CPU usage, and UI was painfully slow as could be expected. After a few reboots, this issue seemed to go away.
Cons: Terrible UI performance, inability to upgrade firmware without valid license (this item from NewEgg does not include a license, it must be purchased separately). Unacceptable loss of network WAN-LAN throughput.
