Greatest review I’ve seen on CZcams, straight to the point. Love it! I’m purchasing one right now! Thanks!

I have had mine for about 3 yrs… LOVE IT! They’re kinda hard to find now😔😢

Nice, take to work so my soda doesn't get flies in it and suck cold beer after hours. My Stanley Vacuum Pint cup with the cap and bottle opener even though a really nice cup has an opening for sipping allowing possible chemical ingress or flies when I walk away onto the shop floor.
