Okay, so I finally caved and got the Stanley IceFlow tumbler after seeing it everywhere. And wow, it does NOT disappoint!

First off, the 30oz size is perfect for my long workdays. I fill it up in the morning with ice water, and guess what? There's still ice when I'm heading home! The double-wall insulation is no joke.

The flip straw is genius - no more spills in my bag! I was skeptical at first but it really doesn't leak when closed. Plus bonus points for being eco-friendly with that recycled fishing net material.

Love the rotating handle - makes it super easy to carry around campus. Fits perfectly in my car cupholder too (though some reviewers say the 30oz can be tight - works fine in my SUV).

Only downside? It's a bit heavy when full, but that's the tradeoff for such good insulation. The mist color is gorgeous though - gets compliments all the time.

Seriously considering getting another one because my husband keeps stealing mine!
