It is easy to insert and remove, and the air-vent design helps release pressure safely. My hot water also stays warm for a longer time.

The silicone material feels thick, flexible, and durable. The stainless steel surface also looks clean and seems suitable for regular contact with hot water.

The stopper fits my thermos securely and creates a tight seal. I no longer have to worry about water leaking while pouring or carrying the bottle.
