I got my Watchman in June 2020 and have had no problems with it at all. The number of AFIB episodes has decreased but I do not know if that is because of the Watchman or not. No way of telling. I am very happy with mine.

My Watchman Device was implanted just a month ago on December 7. While it is too soon to tell if I will have any longer term problems, thus far there have been no issues and I am very pleased with it. The surgical implant was smooth and uneventful. The worst part was the need to lie flat, motionless for 6 hours after the surgery ended. But no adverse reaction, it is mostly invisible to me, with no sensation at all that it is there.
