Mine has been great since the replacement and as customer service told me, the dealer swapped it out with no issues and on the spot.
The woman answering the phone was polite, actually got to an operating version to answer my questions, and was very pleasant to deal with.
One of my nozzles was spraying a straight line and the insertion of a sewing needle immediately put it in mist mode.
I can't wait for the additional nozzles to become available.
