Voyager Tumbler z przezroczystą pokrywą flip & słomką

The twist-on lid seals tight enough that I can toss it in my bag without a second thought, and the double-wall insulation actually keeps my iced drink cold through a whole afternoon of errands. The clear flip lid is a nice touch too, since I can see how much is left without opening it up.

Fits nicely in my car's cupholder and the double-wall insulation keeps my coffee hot for a couple hours. The twist-on lid does feel secure and leak-proof, though the flip mechanism could be a little smoother. Still, happy with the purchase.

Keeps my coffee hot for a solid few hours, which is nice, but the flip lid doesn't seal as tight as I'd like when tossed in a bag. The straws are a good length and the cupholder fit is fine. It does the job, just not flawlessly.
