Works great.
I bought one of these for my mother who is a chemo patient and needs to drink plenty of water. She raved about it and her dehydration problems have eased. So, with my "healthy" new year (after a year of Covid-related isolating), I bought one for myself. I sit at a desk most days, so it is perfect...I silent but noticeable reminder. I use it in the evenings as well in front of the TV. Would definitely recommend.
