You got this!

Love love love this little reminder light! Before getting this light, I had set up multiple reminders on my phone as well as in the water tracker app that I use, and I even created a shortcut in Apple to have my lights come on a certain color at certain times to remind me to drink my water! But I needed a visual cue that I could see at home and while at work or driving. THIS is exactly what I was looking high and low for and couldn’t find anything remotely like it until I found this! I was starting to think I might need to find someone to help me invent one! There’s no separate app to purchase or subscribe to, and the battery is a common size that’s easy to find and doesn’t cost an arm and a leg. The silicone band makes it easy to adjust it for different tumblers. The photo shows it on my 24 oz Hydroflask, I place the light off to the side so it’s not in my way when I’m grabbing the handle. I use this tumbler at home and work and the first time my coworkers saw the little light, they wondered what the weird thing on my tumbler was. Now they get a kick out of seeing my “disco light” go off. It’s amazing how this thing works with its reminders and knowing if I’ve taken a drink recently so it doesn’t remind me. I have had problems getting my hydration in throughout the day since my job is so busy, but this light has been one of the best things I’ve bought. The light does NOT come off the silicone band easily, there is a clip that the band slides through and then you close it and hear a snap sound so you know it’s secure. The only thing that’s not impressive is the cute design I chose. It’s basically a little sticker that’ll probably wear off after use, but I’m not taking off any stars for that.

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.

While the Ulla Smart Light for Water Bottle comes with a hefty price tag that feels a tad excessive, there's no denying its effectiveness. This nifty device does exactly what it promises, reminding me consistently to stay hydrated. And, based on the testimony of a friend who introduced me to the product, the battery's longevity is noteworthy, spanning years. One of the standout features for me is its intelligence in sensing room motion. It ensures that the device doesn't needlessly alert when no one is around, thereby conserving battery. However, I do wish there was an option to adjust the duration between reminders, as I find the intervals slightly prolonged. The brightness of the light is apt, ensuring it's noticeable without being too glaring. I also appreciate the repeated alerts which cater to moments when I might miss the first prompt. While there's undoubtedly room

I love this little thing! It has helped me increase my water intake substantially. I tend to have my water bottle sitting on my desk next to me all day and never touching it. Mostly because I get busy and forget. But my little cactus starts blinking and I pick it up and drink. I have tripled my daily intake since having it.

I love my reminder to drink. It has been an upgrade from my phone alarm because even if I ignore, it will flash at me again when it sense my movement, but have not tilted the bottle to actually drink! I clipped the unit onto the neoprene cover of my gallon stainless jug. Do not use the rubber band that others complain about breaking. (Shown for reference in pocket) My health is noticeably better after 2 days of using!

This device appears to functioning properly, but the concept doesn't work well unless you're sitting at a desk job.

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. :D It 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!! [[My additional tips for drinking more water from my research, if you’re interested, since I have been dehydrated to the point of being off sick from work 4 times in the last year: -Using a wide-mouth bottle may help you drink more during each session. -Aim to drink somewhere around 80 ounces per day; some sources suggest at least 80 oz. or up to half of your body weight in ounces, so if you weigh 200 pounds, you should drink 100 ounces of water…that’s a lot. -Water helps every function of your body, improves your skin texture, and can even impact your mood. -Drink between meals on this schedule: —8-16 oz. shortly after you wake up (helps rehydrate after your sleeping “fast” and activate digestion). —Drink 8 oz. before you get a shower (if you shower shortly after waking up, don’t drink extra water; this helps keep blood pressure stable). —Drink BETWEEN, not with meals, so a half hour before and 30-45 minutes after you eat (a few sips is fine but otherwise you’re filling up with unnecessary liquid and watering down your food; this is an “Eastern medicine” technique). I will pick up my water bottle and pretend to drink so that the clock resets and I can drink again after I eat to aid digestion. —Drink water at the temperature you prefer; I like room temperature water because I have sensitive teeth. If you like ice water, use an insulated cup. —Drink 8 oz. of water 30 minutes prior to starting physical activities and then occasionally during activity, if you’re able. You don’t need really need an electrolyte drink/anything more than water unless you’re working out very hard for an hour or more. —Drink 8 oz. right before you go to sleep; it shouldn’t be enough to wake you up to urinate overnight. —Coffee does count towards your daily water goal, however, it is a diuretic, so make sure this is not your MAIN water source. Coconut water is very good, however, juice, soda, alcohol, etc. don’t count. Drink some electrolyte water before you go to bed after drinking alcohol and also the next morning when you wake up. —I swear by electrolyte additives for water. Some have added B vitamins for energy (like “Liquid IV”) and others do not (like “Nuun” tablets, which I love). They really help no matter how much water you drink per day and provide a little natural flavor to plain water; I typically don’t use more than 1-2 per day. -If you’re starting a new diet, make sure to drink a lot of electrolyte-enhanced water when you start. This is due to losing water weight first and that’s where your body holds salt and electrolytes. This is part of the “Keto flu” that occurs when you start that diet.]]

The watch did not last. The alarm on the watch you could hardly hear it. I have had it a month and had to change the batteries already. Its not even working now that I changed the batteries. Did not like this item at all..

Si se te olvida beber agua como a mi, este aparatito va a hacer que te acuerdes si o si, además es monísimo, siempre lo llevo en mis botellas!

Je l'utilise depuis plusieurs semaines, efficace, je bois 1 l d'eau sur 9h de travail.

Is een goed hulpmiddel om jezelf te motiveren om meer water te drinken.

This really encourages my daughter to drink water, as we all know hydration is key! I love this! By the way this can also be used for adults or teens who need to be reminded to drink water! This is for all ages!

Dudaba con este artículo pero la verdad es que funciona,te recuerda beber,claro está que tienes que tener la botella de agua donde tú te encuentres ya que no emite sonido solo una luz pulsada,pero realmente a mí me funcionó
