Works great. Worth the price.
I’ve only been using Ulla for a week and I love it! It fits all of my reusable water bottles with a stretchy silicone band that does not move at all. It monitors when you pick up your water and blinks when you haven’t taken a drink in 30 minutes. I’m drinking way more water with that reminder. As a matter of fact, when I forget my water bottle somewhere, my kids bring it to me because it’s blinking, so win-win!
