Well name it the ETS 125-2.5, indicating the 250 watts verse the 200 watts of the ETS 125.
Or the ETS 125-2 for 2 amps verse the 1.67 amps of the ETS 125.
In use it actually does make a difference, enough to make me keep it
I rally wish they would have gone 3 amp to 3.3 amp in the Pro5. This could of put it first in its class. With small fine stroke sanders like this more power is so readily apparent. Try the Dewalt 2645 next to the ETS 125 or Pro 5 and anyone will instantly see what I mean. It's easier to get that non swirl finish with the slight increase in power, it just is. The Pro 5 proves this as its very small increase in power(50 watt) does make it better, it's marginal, but enough to make a difference.
