No more daily dehydration headaches!
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.

Water reminder
Works great to remind me to drink my water.

Works for now, but concerned about durability
This thing 100% has been helping me stay on top of drinking water. The only thing I don’t like is that there is no way to stop/pause the flashing – so I can’t have it on the bottle in my bed room and there is no way to turn it off when not in use. The fact that it has been going off ever since unboxing makes me worry about battery life and durability. Without the ability to turn it off to ensure longevity, I am not really sure it is worth the price point as I am thinking I may need to replace it sooner than later.

Staying hydrated and loving it!!
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!!

You will drink more water!
I loved this light. It was helping me drink more water, by a lot!!! But It fell off the rubber band that goes around the water bottle. Somewhere between leaving home and getting to work it popped off. The price is just too much for me to buy another one. So if you think you can keep track of your light I recommend it. But the design needs to be improved on. Instead of a rubber band it needs a clasping band so it can be threaded through a Handel on a mug. The light needs to have a loop instead of a clip so it does not come off the band. But in the end this is an amazing helpful idea! Hope it works out better for others.

Great reminder to get your water intake. Light is nice and bright and captures your attention.

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!
