Nice but lid feels flimsy

The tumbler itself is solid and keeps drinks hot. The slider lid works but the plastic feels a bit cheap. Not a deal breaker.

Leaked a couple times

When I first got it, it leaked a little if I tilted it. After using it a few times, it seems fine now. Otherwise keeps coffee warm.

Good but heavier than expected

It's a nice tumbler but a little heavy for its size. The insulation is great though. Would recommend for desk use.

Late delivery

The cup itself is fine, no issues with the lid or insulation. But it arrived three days late. That was annoying because it was a gift.
