RCBS'S warranty is impeccable for sure, with that said I broke a Lee Aluminum
Press "myfault" that was WAY OVER 2 years old and sent it back to Lee along with a trueful explanation as to what happened and that it was my fault. Less than 5 business days I received a replacement part along with a note informing me it was sent No Charge and Thanks for using Lee Equipment.
With that experience I would surmise their customer service is pretty impeccable. also.
