My MP40 wetside has been binding up a lot and finally some of the plastic bits gave up last week, so I ordered the new QD wetside and then figured I may as well get the new driver as well since it was supposed to be much quieter.
It took me about 5 minutes to switch out the driver, and I have to say that I have been very pleasantly surprised. Every time I walk by the tank I find myself checking that it is still running because it is so quiet
So if anyone is on the fence about it...
