Stanley Trigger Action 0.47L Thermos Trapped in Coffee Aroma

I was incredibly disappointed with the quality of my expensive Stanley Trigger Action 0.47L thermos. The main issues I encountered were:

Persistent Coffee Odor: The plastic cap absorbs the smell of coffee, making it impossible to remove, even with ozone treatment or other methods. This lingering odor taints any other beverage you try to drink from the thermos.

Low Insulation Performance: The thermos doesn't keep drinks hot for as long as advertised. My coffee was lukewarm within a few hours.

Poor Quality Control: The plastic cap feels flimsy and cheaply made, not what I would expect from a high-end brand like Stanley.
