I have two 14 oz mugs and my husband has the first travel mug and we love them.  I was excited to get my own travel mug because the 14 oz doesn't fit in my car's cup holder and trying to balance a mug while driving probably isn't the safest.  I was excited about the larger capacity and the slide lid (the other travel lid does expel hot liquid when pressed open due to pressure in the cup and can be messy).  I like the new travel mug and the reason for 3 stars is that is still doesn't fit in my cup holder and without a handle, it's girth is a little difficult to hold with my tiny hands.  This mug would be perfect with a smaller base and a handle near the top, so I'm still balancing my 14 oz mug on my morning commute, which actually sits on top of my cup holder better than the travel mug.
