"Keeps ice for over 24 hours"
I tested it on a hot July day — left it in my car and came back 6 hours later and still had ice. This thing is exceptional. I drink so much more water now just because I enjoy using it. The flip straw lid is incredibly convenient.

"Best tumbler I've owned"
I've tried the expensive ones and this performs just as well at a much better price. No condensation, fits my cupholder, and the lid doesn't leak when I toss it in my bag. The 40oz size is perfect for a full day without refilling.

"Great quality for the price"
Solid construction, good weight, easy to clean. The insulation genuinely works — my tea was still warm 8 hours after I made it. Lid fits securely. Would have given 5 stars but I wish the straw was slightly wider. Minor thing overall.
