Same here...very happy. Mine were replaced on 11/27. A lot of miles for me so far in less than a month. 2,355 miles driven including an 1100+ mile 2-day road trip this past Friday & Saturday. It might be a good idea for a poll to actually figure out the success rate and if it trends towards certain builds... Mine is a March 2018 Model S 100D with Stock 19” Slipstream Wheels/Stock Tires.
