Permanently turn off new Google Maps and go back to old one

75 I found new Google Maps slow, useless (routes with only two points) and wrong. Is there any way, I can turn it off completely and go back to favored old Google Maps? Or is this — as with everything in Google — one way trip? I found Google Help text on this matter, but it seems useless.
