Query: :(

Pros:It holds liquid when sitting on tabletop.Cons:-The plunger does not work well to keep coffee grounds, or tea from floating up into your drink.-There is no seal or lock to keep the plunger fully depressed-- liquid might not leak from the drinking spout, but it will spill everywhere out of the plunger's hole.-Does not keep liquids hot very long.Don't waste money on this product.
