Frequently Asked Questions About Insulated Tumblers

Stanley vs YETI?

Functionally similar. YETI has durability heritage, Stanley has the moment. Both excellent for cold retention.

Are expensive tumblers worth it?

For insulation alone, no—$25 performs nearly as well. You pay for brand, warranty, durability.

Why does my tumbler smell?

Bacteria in straw, lid crevices, or residue. Deep clean with baking soda, scrub all parts.

Can I put coffee in with a straw?

Yes, but straws may cause staining and hot liquid can burn. Most switch to lid opening for hot.
