Query: Nice mug, but...

I purchased this mug for my husband, and purchased 4 of the Dragonfly - Just Believe Ceramic Travel Mug from another seller. Except for the design on the mug, the mugs appear identical. What puzzles me and stops this from being a 5-star review is that the lid for this mug does not fit tight; its so loose you cannot tip it to drink from it without the lid falling out. So much for a travel mug.
