“I'm enjoying the insight I'm getting from my Lucy. It's definitely helped me drink more water through the day, and made me realize that I was never actually taking in as much as I should. The measurements it takes from the bottle is pretty impressive. My only complaint is how it screws onto the bottle. I feel like I have to turn it so many times to get it on all the way, and even then it leaks a bit if I add a powder to the water that I have to shake to mix. I've only tried it on a glass bottle. I'm not sure if it would attach better on a steel.”
