It has not only gotten me to start drinking water on a more regular basis, but it has been a huge conversation starter with others about drinking water. Love the design, the function, and the conversations it has started! Thank you!

I bought one for a gift for a friend with dementia. It has helped her remember to drink water. I also bought one for me because while I am working, I tend to forget to drink. I would have preferred an adjustable strap instead of but a stretch strap. Some of my glasses are too big for it.
Great little silent reminder

This really does remind me (and my coworkers in my immediate vicinity!) to hydrate more often. It's a friendly, silent little "pest" saying, "Pause, and take care of yourself!" I am drinking at least 2 or 3 of the Insulated Water Bottles (I bought on this site), and without the reminder, I would maybe drink 1 or 2 smaller bottles while at work. It continues to remind me at home as well. It doesn't have an on and off button, so I'm not sure if it blinks periodically at night or not, since I'm asleep. It says the replaceable battery works for 6 months.

Get subtle hydration reminders to help you drink eight glasses a day. Ulla turns your drinking vessel into a smart water bottle. The silicone band fits over a bottle or glass, with an accelerometer inside to track movement. Go more than 30-40 minutes, and Ulla’s light will blink.


Ulla turns your drinking vessel into a smart water bottle that gives you hydration reminders during your busy day.

It’s a silicone band that fits over a bottle or glass. Inside, an accelerometer, which tracks the band’s movement, knows when it’s been a while since you’ve taken a sip. Go more than 30-40 minutes without some H2O, and when you’re nearby (the band’s sensors will know that), Ulla’s light will blink.

Several of us tried it out here at Grommet headquarters, and were grateful for the reminder to stay on track to drinking our eight glasses a day.

Put Ulla in place, and you don’t have to do anything else. Just drink. more Their Story
