I was a little worried it wouldn't fit my car’s cupholder, but the slim design slides right in. The splash guard spout actually works perfectly for taking big gulps without any mess.

The locking push button is a lifesaver—I toss it in my work bag daily and not a single drop has leaked. Slim enough to slide into the car cup holder without wobbling, and the splash guard means I can chug without worrying about messes.

This is my third week using it and the splash guard spout really works—I've thrown it in my backpack every morning and not a single leak. The slim design slides right into my car's cupholder, which is more than I can say for my old bulky mug. Worth every penny.
