I highly recommend Herr Gregory Shir's redesigned keyboard because it equalizes the upper width of the white keys.
--- Ms. Alvina Louie playing and commenting on Mozart piano
Because intervallic distances are more predictable, the C# (Db) and D# (Eb) keys are technically more accessible in all hand positions,
irrespective of individual hand anatomy or finger patterns.
--- Ralph Alberstrom
It seems there is a manufacturing defect built into piano keyboards.
Believe it or not, the intervals on the standard piano are NOT equal!
Lay a finger between C# and D# notes, now lay your finger between F# and G# - you can feel the difference between the two pairs.
Between some white and black keys there are different distances. It's only about 3mm, but that is a big difference when you are trying to sightread without watching your hands.
