Flex Sip Coffee Mug 16oz or 20oz

Overall good bottle

I really like this bottle for a number of reasons, the biggest being that it's completely dishwasher safe and you can disassemble the lid to make sure it's totally clean (I don't like to think what's in lids that can't be opened and cleaned...). However, you have to be sure to put the red seal back in correctly or the bottle will dribble a little when you sip. No major leaks and it's an easy fix but good to know.
