Mine leaks
My "Nissan 15.9-Ounce Travel Mug/Food Storage Jar" Kitchen; ...eachLEAKS out around the seal between the drinking lid and the mug. The problem occurs when the coffee cools and condensation forms inside. The problem is getting worse and I've had coffee leak all over me many times. I've tried drying the seal and screwing it tighter and nothing works. I suppose this mug may be defective and will seek a replacement or refund.
