I should have read all of the reviews.
When I first received the product I was thinking, hmm looks really cheap. (Check the photo I uploaded) The product worked for a few months and really did help me drink more water. These days, it won't stop flashing (Rather than flashing at a 30 min interval), rendering the product useless. Looking at other 1 star reviews, this is definitely not an isolated occurrence and occurs often it seems. For this price point, I expected a more substantial product. I would definitely recommend most people to steer clear.
