the only thing that the new HD Random Orbital has in common with this one above is part of the body is red and also has the top piece which is similiar to the rupes like the one above, the on/off switch is located on the top end of the polisher where the end of the black grip is on the one pictured above. also, the speed dial is also near the end of polisher but on the left side in which it would be where the bottom left grip piece above but to the right. the body style is similiar to that of the old HD/HF DA. it's also 710 watts IIRC...
