Mine was sent in right before deadline and got it back in my hands on April 10th. I emailed Leica NJ about 5 times. The repair was put on rush order after the 5th email on March 26th, received $0 invoice on April 4th and the camera on the 10th.
Despite the long wait, the communication from NJ was always replied back promptly within a day. Props to their customer service team.
