Great bottle for measuring water intake

This bottle helps me drink all the water I should every day.  I've used it almost daily for the last few months.  It is easier for me to track with one bottle than to try and keep track of how much more water I should consume with multiple glasses of water each day.  The straw was a little tricky for me at first and is my least favorite part of this bottle.  I do not like having to squish it down to close the lid or to pull it back up into place, that's the only downfall.  I did need to buy an extra long straw brush because the one I had couldn't quite reach the middle of this straw.
