Would this fit a wide mouth HydroFlask?

Yes! It fits my 32 oz wide mouth Hydroflask perfectly. :)

How do you change the battery?

Simply take off the cap and you will be able to remove the battery and replace it with a new one.

Will it work if you use a straw on your water bottle? To track your drinking

Yes as long as you move the bottle/pick it up. It works by motion.

How long will the light blink to remind you to take a sip?
