I give it a 4.5 (but there is no half star option). I love my full-sized and mini travel mugs. So lightweight, easy to carry, easy to sip from, easy to clean, and perfect to drink from and a pleasure to hold. Highly recommend. Only reason it gets a 4.5 and not a 5 is bc the color was disappointing on the large mug. Very muted and dull. Was hoping for more of a sunset vibe and instead it looks like a cloudy, dull day.
