Here's Why Customers Love Ulla

⭐ ⭐ ⭐ ⭐ ⭐

This tiny little gadget really works!!!

“ I went from drinking ZERO water per day (literally) to 50 oz just because of my Ulla. There's something about that little light flashing that truly reminds you to drink when you forget to otherwise. ”

- Lorita M.

⭐ ⭐ ⭐ ⭐ ⭐

A MUST HAVE for anyone with fitness goals.

“ After using Ulla at my desk job, my water intake is way higher than it was before. Just from drinking more water, I’m noticeably more attentive and productive at the office. I get home after work with more energy and have a much easier time getting to the gym. ”

- Gitta B.

Super cute, work without any issues.

“ I ordered 2 Ullas some months ago, one for myself and one for a gift. No regrets! The devices are super cute, work without any issues and definitely keep us hydrated. We actually have a small ritual in the office - whenever either Ulla reminds us for water, the person shouts “Watwr!” and everyone drinks some water (everyone started drinking lots of water daily) and the day just flows! ”

- Heidi I.
