This Love Tester is the perfect gadget to sell to teenagers and foolish people. It requires a male and a female to hold the appropriate end of the Love Tester, and if the thing lights up, the two of you are in love.
Depending on how high the love goes (our love doesn't go to eleven), the two of you will either be soul mates or should get divorced immediately. Or it could be somewhere in between. No same-sex love here though, apparently.
And unlike the Inch Perfect, you can find out how deep your love goes without having to bump up against your cervix.
