If you’re a parent, chances are you’re concerned about your child’s internet activities, from who they’re chatting with to the sites their visiting to the amount of time spent online. We propose a gadget that could help: Best NetGuard. It’s a small remote control with two buttons: “ON” activates Best NetGuard, disconnecting your child from the internet. The “OFF” button re-connects them. The device works by enabling/disabling the ethernet connection on the PC. No software or tools required, and it works from a range up to 75 ft. Available for $40 USD.
