I have never had a problem with breakdowns, I’ve had a few problems, but nothing that has needed too much involvement by the spanner men.
I had a couple of grand’s worth of work done on a TK SMX I owned, but it was ten years old by then and never let go, it just needed a load of innards replacing.
I’ve had sensor alarms go off on the PBT ones, but nothing that ever stopped it doing its thing, most of those were when it was trying to heat a protect from freezing load in winter, rather than cooling issues.
So I should probably add that to my CV then, don’t know SFA about the workings of a reefer, but in spite of that I’ve never had a problem with a load.
That should open up a few doors for me
