Great tool

3/2/2018 by Colleen

I needed to drink more water at work, but keep getting to the end of my day with the same bottle of water I started with. This little light is not complicated to use and really works. Since starting to use it, I get through 3 bottles every day. There are no settings to mess with. You just hang it on your bottle and start drinking. It keeps track of when the bottle is picked up and tipped in a drinking motion. If you don’t drink in a 30-40 minute stretch it blinks rapidly. It really does get you attention even though there’s no sound. I’ve noticed it from across the room. I find myself being more mindful of whether I’m drinking throughout the day. When you drink, it gives you a gentle flash of light to acknowledge the action. It’s powered by a button battery and is silent to prevent complaints from co-workers. If you struggle to remember to drink water this will help remind and train you to get more water through out the day.


Don’t do what I did

I love the product. I do wish it was easier to move from bottle to bottle or had an extra band. I left just the band on my bottle and put it in the dishwasher. What came out was a skinny long round band that will fit over by milk jug. How do I replace the flat silicone band?


Love this. Works great with people who have dementia

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.


Good but Hoping for more

I love this idea. But as a recent bariatric patient that has to sip constantly, it would be great if it had a programmable timer. Then I can set to take a sip every 15 minutes or so. Bariatric patients can’t drink a lot at a time because their stomach volumn has been drastically reduced. So “sipping” a lot is required to meet the 48-64 oz per day. Drinking enough each day is one of the biggest problems post surgery. A constant reminder every 10-15 min would be very helpful! I can have my water bottle near me, but forget to sip often enough. Everyone needs to drink more water each day, but with a programmable timer you’d open up a whole new market with bariatric patients!! Great product .. hope it evolves!

I've been using it on my water bottle at work and it definitely has me drinking more.


Really helpful

I do love this accessory! Only one issue is that I use the straw lid on my Hydroflask so I have to remember to tip it up so Ulla knows I took a drink.


Hydration reminder bottle accessory

Reminds me to drink morE water. However, it has come off the band 4 times


For one spot workers

I love how it works when I’m sitting at the computer or my easel or even reading or watching TV!
However, I discovered on a road trip that the movement of the car makes it think I’m drinking so
it doesn’t flash for me - that’s the only reason I gave it only 4 stars. It works great otherwise!!

The Ulla Story

Your water bottle is blinking. Take a sip.

Hydration reminder

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. Read More Read Less
