I was very pleased that the air filter arrived significantly before the promised date. I was amused that I received the "your item shipped" and "item delivered" notices a few minutes apart. I was not all that thrilled that the "Donaldson" filter advertised, that I ordered, but the filter I received was a "Baldwin". nothing wrong with Baldwin, just Donaldson was specified by the equipment supplier. I was pleased that the part number I ordered and received actually fit, I wasnt sure part number
