Review: 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 😉 Review: i bought this for our great nan, she is 94 and keeps forgetting to ... - 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. ## Features - SMART LIGHT FOR WATER BOTTLE: Ulla is the world's first smart hydration reminder water bottle attachment!
