MOTORINO DIAVOLO sequential Gear System any good?

Happy New Year to all,
What are your thoughts on this piece of kit?
I am looking at this as I am currently nursing a broken left hand, would it make changing gears lighter or is there really no difference.
Sensible answers will be studied, while silly comments will be ignored
TIA
