Lucky. Working in repairs I was only seeing the ones that didn’t work, and I’ve seen failures of just about everything. It probably skews my experience.

One time upgrading workstations, 4 of the 20 Corsair kits were sent for RMA. Those aren’t great odds.

I would guess that soldering them to the board reduces the points of failure, the slots can and do fail. However, I’ve also seen soldered components coming off as the cause of failures, but it is usually a part that gets hot combined with a design flaw.
