I've seen some reviews from people who had issues with some forks, particularly the 90 degree forks that I've also used. I rolled the dice because I knew this was going to be a problem and just wanted people to know that this is a fixable problem. The plastic edge on this unit is strong so you can quickly and safely remove the edge with a dremel so it will work with whatever you plug it into. Just be careful not to get too deep into the device itself. After modification, it works fine with the extension cord I connected it to.
