I have a STRE-88811 that I have had since October 2022.  I left this flashlight outside in West Virginia winter from January - July 2023 in my driveway running it over every day.  This was an accident and I thought it was lost.  I then used it daily for mechanic work and law enforcement up until July 2025, when I again thought I lost it (Fell into my couch).  I then found it again back on June 3, 2026.  I, stupidly, proceeded to leave it outside all summer.  Through rain, 100 degree heat, all kinds of issues.  I finally brought it inside and charged it. It initially did not work (this month October 2026), but over the course of a couple days it turned on by itself.  It then only had its low-light function.  It now has fixed itself and has its full low and high beam function and is charging.  I could not recommend a more durable flashlight in my entire life.
