ULLA Drink Water Reminder, Smart Light for Water Bottle, Fits Most Bottles, Lights Up when Time to Drink, Hidrate Smart Water Bottle Reminder to Drink, Smart Hydration Reminder, Water Tracker - CACTUS

I absolutely LOVE this product!! It’s simple but impactful and it has absolutely helped me drink more water throughout the day than I have in the past several years. I have tried pop-up reminders on my work computer (Outlook), apps on my phone, reminders from my FitBit and posted signs near my desk but nothing helps like this blinking* light. I already had several reusable water bottles so I sought an accessory; this item is much cheaper than “smart bottles” and doesn’t need washed. :DIt fits on water bottles of various sizes. The reusable bottle I have pictured (I have 3 of them) has a diameter of almost 3 1/2” (nearly 9cm) but the band also fits on a standard 16.9 oz. bottle and bottles larger than the one I typically use.The light blinks every 30-45 minutes to remind you to drink. After you drink it will light up slowly and turn off slowly so that means it has recorded you drinking and reset the clock. It does not blink all night while you sleep; the instructions explain it will go through about 2 blinking cycles and as long as it doesn’t sense movement, it will stop blinking until it senses movement again.The only caveat is that you need to have the bottle in front of you in order to see it - it doesn’t make any noise (like yell at you, which I would also likely respond to). So make sure you take the bottle from your work station to other rooms where you spend time outside of work. I work from home so I grab my bottle and move it at the end of the day.This item is currently unavailable, but the last time that happened they had some available a few weeks later; I hope there are more available soon!!*This product may not be ideal for those with light sensitivity or conditions like epilepsy because the light flashes quickly. If flashes about 10 times, then stops, and repeats that series twice more.*Happy drinking!!

THIS THING IS AMAZING. I've had it 1 month now and not had a single dehydration headache!!MY BACKSTORY:I carry a water bottle everywhere and would sit with one on my desk at work daily, but I rarely would drink out of it. I simply carried it because I would suddenly feel thirsty if I didn't have it. I get a headache around 2-3pm daily like clockwork. I suspected it was dehydration since the rare occasion that I did manage to drink enough, I didn't get a headache, but I couldn't keep up with it. I tried various tracking systems, including the ones with the time printed on it to pace myself. None of it worked because I physically needed a reminder. I thought about setting a timer, but that would be cumbersome, disruptive, and not dynamic enough to shift with daily life. I found this reminder and was hesitant to pay $25. But, it was a lot cheaper than "smart" water bottles and I knew taking Motrin and/or Tylenol daily was not healthy. The cost was worth it after feeling this headache-free relief!!SIZE:It has a silicone band that fits well on my water bottle, which is about 3 inches in diameter. It definitely has enough stretch to fit on a 1L Nalgene, for example. The device itself is about 1.5" tall, 1" wide, and 3/8" thick.HOW IT WORKS:I timed it when I first got it to see how the cycling works. Every ~35 minutes it strobes for ~5 seconds, then is off for ~5 seconds, alternating that cycle for about a minute before it resets the 35 second clock. I usually grab it within those first 5 seconds, but if you're not around and it does 2 full cycles of 35 min/1 min flashing, it turns off until you drink again. It also resets the clock every time you drink and has a light that blinks whenever it registers you taking a drink. It's gotten to the point that my body has internalized the clock a bit; on many occasions it started strobing as I was reaching for a drink on my own!MY CONCERNS DIDN'T END UP BEING ISSUES:- I thought the "just drank" light would get set off a lot carrying my water bottle around, but that hasn't been an issue.- It also has a light sensor, because it doesn't go off in the dark. I can keep it on my nightstand with no issues- My water bottle has a straw, so every once in a while my sip is a little too still for it to register, but that's been only maybe 5 times in the last month.- It's also perfect everyday use outside of the office - I don't have to deal with alarms and it dynamically updates as I drink.- I keep it on all the time, and haven't worried about it falling off. I did take it off twice when I want on a day-long outing where I knew I'm going to be drinking a lot on my own and didn't want it to interfere with the frequent in and out of my backpack.

I take my water bottle every where go but I never remember to actually drink the water. 🙄This was working great to remind me but I lost it after 3 weeks. The clip that attaches the device to the strap is not good enough. The device can easily fall off and be lost.I have to believe the company isn't very concerned about this problem because it's been reported for the last three years and they haven't bothered to make a simple design change.I'm planning to use Gorilla glue to close the clip on my new one. I hope it solves the problem. I refuse to keep buying if I lose it again. 🤞

I love this light. I fill up my water daily but forget to drink it. I love the remind. It’s pricy in my option but I you need water and can’t remember it’s great.

Like many of the reviewers, I've tried phone reminders, special time-stamped bottles, different types and sizes of bottles...everything. This little timed light is the thing that has kept me consistently drinking water throughout my day finally. I will say I think it works best for people who have jobs that keep them at a desk or close to one place throughout the day because moving the bottle a lot, or being out of line of sight from it for long periods, would create issues. I love it and it's done the job perfectly for me.

I have kidney disease and water intake is a huge part of each day. I often forget to regularly drink throughout the day and this little light has worked great for reminding me; However, it should be noted this is my 3rd purchase as the 2 prior lights fell/slipped off. The light slides onto a silicon band, but there's no closure so after a while it can ride up the band and fall off. But, it's such an awesome, affordable light that I keep replacing it. Great product, but product design could be better in this regard.

The media could not be loaded.  Best idea they’ve ever had whoever it was very very good. Can’t live without it. Fantastic you’re one thing to know is if it’s dark it will not work because you think you’re asleep obviously in bed so if you’re in a room and it isn’t going off and it’s a dark corner, I would advise you to put a light on Apart from that, it’s fantastic

In the office I drank a lot of water, working from home I’m more sketchy remembering to fill my bottle.I was getting headaches I knew largely from not drinking brought water.Saw this and thought maybe a gimmick but let’s try. It 100% works. I will be at my desk and it flashes. When I finish the bottle I go straight off and fill it.So if you’re struggling to remember to drink this little thing will help you.

Made a great gift for a good friend!
