This is supposed to be newer and better version than the M65. However, I found three things on the new one that were disappointing compared with the old one.
1. the control lever on the M70 is shorter than the M65 lever which makes it harder to make small adjustments to the temperature.
2. The spout on the M70 bends backward toward the body of the unit which reduces the arc of where the water flow can be directed by rotating the spout.
3. There appears to be a flow constriction in the new one which is more restrictive than the old one (if there is one in old one). This makes using the brush less effective when washing dishes and when moving garbage in the sink toward the disposal.
I have used a dish master for more than 50 years and love it. I will continue to buy them in the future even if they are less effective than the old ones. I just wish they would not degrade the performance as they develop new models.
