Product review (4 stars): Drop in replacement for Badger-5
It comes with a new collar but I didn't bother to replace that, just used my old because I got an old sink, when I get a new sink, then I will use the new collar.  It was really simple, I just twisted off my old badger-5, twisted on the Fridgidaire, hooked up the existing hoses and I was done. OK so the prep included knocking off the dishwasher hookup plug, and moving the power cord from old unit to new unit, nothing to it.  I picked the fridgidaire because at the same price, this unit comes with a noise jacket, I was hoping for quieter operation, and it does, but am not sure because it's new, I should had taken measurement but ooops. At the same HP this fridgidaire takes a few more seconds of grind time to drain my stuff than my old Badger-5, not a deal breaker. See how long it lasts.
