ULLA Drink Water Reminder, Smart Light for Water Bottle, Fits Most Bottles, Lights Up when Time to Drink, Hidrate Smart Water Bottle Reminder to Drink, Smart Hydration Reminder, Water Tracker - CACTUS : desertcart.co.uk: Sports & Outdoors

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: 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!
