Great little gadget that really does work.
A great little reminder to get that hydration in. The flashing light picked up by movement is really noticeable and does do its job. I bought this for my Son who has Cerebral Palsy and one symptom of that is he doesn't get the signals that he is thirsty so this is a fantastic aid for that. I bought it when it was on offer for half price, I think! I wouldn't have bought it at full price then but probably would now I know it does its job. Also, my son had an acne problem, he was under a specialist for it and since he has upped his water, his skin has literally cleared up, it took around 8 weeks of constantly drinking water throughout the day, all day every day but the results are amazing. So drink more water folks, it's good for you ๐

i bought this for our great nan, she is 94 and keeps forgetting to drink, she hasn't used it yet as she is currently in the hospital but as soon as she comes out she is going to be using it. i have tried it myself for two days and i must say that this little thing has really made me drink more, it flashes when you got to drink and it wouldn't give up so you feel i better do it just so it stops blinking, once you had a drink it has a little flash light blink once just to say well done and from that little thank you feel , i feel very much appreciated for all my efforts. i can't fault the product i think it is fantastic and i think it is going to be amazing help and reminder for our nan.

I love this product
I love this product, although I do not believe the light is able to sense (as they claim) when you're not in the room and it keeps flashing all the times.

Ulla Smart Hydration Reminder
I bought the ULLA Light up Water Bottle Reminder for about ยฃ21.02 on Amazon. Itโs a small attachment that lights up to remind you to drink water regularly, and it fits different bottles with a silicone band. Itโs quite simple to use since thereโs no app or setup, just attach it and go. The light is subtle and not annoying in the office. It feels handy for staying hydrated, though itโs very basic and the band can be a bit fiddly at times.

It works!
In the office I drank a lot of water, working from home Iโm 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 letโs 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 youโre struggling to remember to drink this little thing will help you.

I love this little device
I had purchased one of these a while back and loved it, but somehow managed to lose it between home and work. I've been suffering from headaches again, and I tend to get them when I'm not drinking enough water, so I decided to get another one. If you are like me and forget to drink water, as much as you have good intentions to do so definitely get one. I had tried to put reminders on my phone, but then you pick up your phone, get distracted by it and lose focus on what you are doing. This way, whenever I've not drunk in a while, it flashes at me and I take a swig of water and get back to what I was doing. LOVE IT!

Durable and really does increase your water consumption!
This thing is awesome and I have purchased 2 more for friends! It really helps me drink more water. It goes off every so often when you don't drink, and sometimes I worry I miss it so I drink more just to be sure haha! Sometimes it doesn't register that I drank and continues blinking. I think it might be when it is on the side of my bottle, vs the front or back, but need to test further. My friends got left in the street over night when it rained and it still works great! I love that it goes to sleep when theres no light, as soon as I get up in the morning it wakes up when I move around!

Buen invento para gente que no beba
Me he comprado este aparito y realmente no esperaba nada, pero de verdad, es genial. Trabajo en un despacho y tengo la botella con el aparatito siempre en mi mesa y desde que lo tengo, bebo por lo menos 2 litros al dรญa (antes ni llegaba a beber 1 litro) y estoy muy contenta.

Amazing!
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!
