Honestly it's popularity doesn't surprise me. I used Stanlies everyday to make coffee for work and take food to work. My mom used to swear by them. I leveled up and bought different products after a while but did use Stanley for a long time. They're standard "good" thermoses. Bastards putting lead in it! I knew lots of men at work who used them. I would be shocked if anyone at work didn't at least know the brand.
