Old guy likes new things
So far so good. Navy trained electronics technician many moons ago, I learned to solder and tape wire joints... years later, I used heat shrink... this was the next evolution of that. I have siliconed heat shrink when I did not have heat activated heat shrink with glue for applications. That was usually larger wire and expensive... just like these. We shall see how long they last when the weather warms up and I start repairing my trailer lights.
