I got the Ulla after checking out all the different hydration assistance tech.
I totally LOVE my Ulla, I tend to forget to eat or drink during the day. I've done this all the time I worked and now since I retired.  I've been having problems with being dehydrated lately so I researched the tech to help you stay hydrated.  I felt the bottles that remind you to drink were too expensive and I didn't like having to put all of my water bottles, mug, and whatever, away and use only one.  When I first round the Ulla i was so happy!  Once I tried it i was thrilled!!!!  It fits easily on every bottle, mug, can, or anything i drink out of!  I am getting in the habit of drinking whenever I see a flashing light 😊.  It is noticeable when my bottle is On the end table or to the side of me.  It is far from annoying or irritating it is fun to use and I enjoy the single flash that I take as meaning &#34;Good job&#34;!  It is also much less expensive than the others i checked out.  I can't think of any cons except right now I can't find it because I keep changing what it is one. 😊  OH, maybe I should get a couple different colors and sayings ☺😊😁😀😊☺
