Have them fitted and they do what they are supposed to do. There is a drawback for drivers of a LHD car. The device interferes with my knee (left leg most of the time idle off course).I guess RHD drivers are less bothered.
Kind regards,

I'd not thought of that, but you are quite correct, it could be annoying.
I always thought that LHD Cars should reverse the pedal layout.
