Rally 蛋白質搖搖杯

My coffee stays hot through my entire morning workout, which is exactly what I needed from a shaker. The pop-open spout is super convenient when I’m cycling and don’t want to fiddle with a cap.

I was skeptical about it keeping my coffee hot, but the double-wall insulation really worked for hours. The pop-open spout is super convenient for one-handed drinking at my desk. Definitely a solid shaker for daily use.

The twist-on lid with the handle loop is genuinely leakproof—I tossed it in my gym bag sideways and nothing spilled. Kept my smoothie cold for a solid three hours, which is all I really need. Only gripe is the spout takes a bit of effort to pop open one-handed, but it's a fair trade for the seal.
