Review on FOVAL Power Step Down 220V to 110V Voltage Converter with 4-Port USB: Travel Adapter for 150+ Countries Worldwide (Red) by Gilbert Pfaff

I bought this unit because it looked universal and we travel between many countries. We've been using it for about 2 months, fairly consistently for 1 month, and it's become very sensitive. You unplug and plug the cable back in, and you can hear electricity clicking between the power cord and the device. Sometimes it stays on, sometimes not. We're afraid to touch a connected device as it can take a few minutes to get it working reliably again. Big disappointment. I bought a strip from another manufacturer. It's been great when it's reliable, but I need that kind of performance to get the job done and we just can't expect it to last.
