I just noticed that the R52 is only rated for 0c and the R52H and all other MT products seem to be rated for at least -20c or better. I know the R52 has been out for a bit but I would like to here from someone using them in a very cold climate. We can see -40c on occasion here and If it is going to be an issue Iād rather swap them out before winter comes ![]()
