Review on Soteria Webcam Cover & Microphone Blocker - USB Data Blocker & Privacy Kit for Enhanced Personal Security - Ideal for Home or Travel - Protective Gadgets for You & Loved Ones (Black) by Jason Dahlkemper

1. Webcam cover. The webcam cover is a small piece of plastic with an adhesive on the other side that opens and closes. It covers my webcam well and the adhesive helps keep it in place easily. I tested it on my webcam and the video was completely blacked out. No complaints.2. Microphone Blocker - works well with one caveat. I plugged it into the headphone jack and tested it during a video call. There was no sound at the other end! Hooray! After that I really wanted to test how well it works, so I went into my laptop's audio settings and made sure the mic wasn't picking up sound, but as soon as I changed the mic to a different one and then turned it back on, the mic started sounding again record. Soooo, don't do this if you want it to block your mic.3. USB Data Blocker - This seems to work fine. It looks like the USB connector still has two data pins inside that are used to transfer data, but after some testing no data was transferred! Very impressive. All in all, this is a useful set when you're on the go or using your devices in public places. All three are designed to be low profile enough to stay connected or slip into a pocket.
