Query: Mug LEAKS

We decided to order all new travel coffee mugs and ordered a wide variety, including two of this Copco Thermal Travel Mug (one in this pink and one in gray). We are extremely dissatisfied with these mugs. BOTH leaked where the mug changes from stainless to the plastic edge and then again about (less than) an inch higher where you screw the cover on. Let's just say, on my way to work, in the car, I ended up with coffee dripped on me from this mug - not too happy. Tested the other one when i got home to see if it was an isolated incident, and it was not - both mugs leaked in similar places.
