What's stopping them, if they need faulty 4201s? I can send the pile

I installed a 4201 in my 27 in 2003 and replaced it in 2018. 15 years
without a fault in the electronics. I did however freeze the LCD one winter
which needed to be replaced by the factory.
Sold it to USA for a few dollars. Haven't heard that it failed.

How cold does it need to get to damage the LCD? My glider is stored in an unheated hangar in the winter here in Vermont, sometimes goes down to -20C or worse, but so far no damage to the 4201 LCD.
