Weird... maybe they are different where you are? Older models, or not installed/adjusted correctly?
I use these all the time (they’re pretty much everywhere in the U.K.) and haven’t experienced this unbalanced pressure issue.
They always seem pretty much equal pressure on each side to me.
With large hands, there's an extra degree of difficulty to avoid touching the sides and the bottom. It still leaves you with wet wrists and damp fingers.
