The message
from "John" contains these words:

I have noticed that those cheap breakers (with the vertical motor)
weigh up to 6kg but the impact force or 'blows per minute' is often
lower than a branded 2kg drill/breaker.

They still go through brick and concrete like a pound of gooseberries
through a two year old.
