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 š

Useful little gadget for those of us who forget to drink.
Like many women, I suffer from chronic UTIs. This little gadget is invaluable to insure that I drink enough to minimise the amount of UTIs I get. The light is bright enough, the sensors work. For less than 6 quid it is defo worth it. I am going to gift one to my mum.

Abit expensive but it does do what it says. If you don't take a drink regularly, it flashes a constant reminder. Water intake has definitely increased!

Great but didn't help in my situation
I brought this for my autistic son who is struggling to remember to drink water at school, and to give him some more indepence without adults having to keep remind him to drink his water. It's a great bit of kit if you can keep your eye on it. Unfortunately it's not helped my son remember to drink at school as he does get distracted and still needs reminding to look at his bottle. I think it would be great for adults who maybe work at a desk where they can keep the bottle in view.

EXPENSIVE AND NOT WELL THOUGHT OF.
POSITIVES FLASHES AT INTERVALS NEGATIVES EXPENSIVE ā¢VERY WEAK FLASHING LIGHT ⢠ULLA IS HELD ON BY A VERY WEAK ELASTIC BAND. HAD TO REPLACE WITH A STRONG ELASTIC AFTER SEVERAL TIMES , ATTACHING AND REMOVING FROM THE VESSEL. SUGGESTION ⢠ELDERLY PEOPLE WATCHING TV DONāT EVEN SEE THE ULLA FLASHING AWAY UNLESS CONSCIOUSLY WATCHING AND WAITING FOR IT TO FLASH ⢠CANT YOU IMPROVE THE ULLA WITH A SHRILL THAT GETS LOUDER AND LOUDER UNTIL YOU DRINK FROM THE VESSEL ITāS ATTACHED TO? MAKE IT VIBRATE THAT GETS STRONGER ? IM SURE WORRIED RELATIVES WOULD PAY FOR AN ULLA THAT DID THE ABOVE. I WOULD. AND I DID MUM DOESNT SEE IT FLASHING. ITSTOO WEAK. THIS IS A BRILLIANT IDEA ONLY ON PAPER. YOU NEED TO REDISIGN MAKING IT VIBRATE OR SOUND. ALSO NEEDS TO BE ATTACHED TO A STURDIER BAND

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.

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

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!

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!
